Andersen 100 Series gliding patio door: how to identify it, its handing, and where repairs go

Andersen's 100 Series gliding patio door is made of Fibrex composite material inside and out, with one panel that glides and one that stays put. Andersen makes no three- or four-panel 100 Series door in one frame. Its insect screen is handed the same as the door; its rollers, locks, and weatherstrip are not. The roller depends on the date the door was made, and the lock guide depends on whether it has Tulsa or Afton hardware. Track cleaning and lock adjustment are done with the door in place; inspecting rollers takes the panel out, which this site leaves to a professional.

The short answer

Andersen's 100 Series gliding patio door has one panel that glides and one stationary panel. Andersen says 100 Series products are made of its Fibrex composite material inside and out, and calls this its budget-friendly gliding patio door. It does not make a 100 Series gliding door with three or four panels in one frame.

Two facts decide which parts and guides apply: the date the door was made, because Andersen changed the 100 Series roller in March 2010, and the hardware style, Tulsa or Afton, which decides the lock guide. Track cleaning and lock adjustment are done with the door in place. Andersen's roller inspection takes the sliding panel out, and this site leaves that to a professional.

Every statement here comes from Andersen's own documents, opened on November 5, 2026 and linked at the bottom. It applies to the 100 Series gliding door only. This site is not affiliated with Andersen.

Is it a 100 Series?

The label. Andersen says its Product ID label gives the Series, size, color, glass type, and more. It says 100 Series labels vary by product type and manufacturing date:

  • labels beginning with SLD, from 2008 to 2018;
  • labels beginning with 122, from mid 2015 to the present;
  • labels beginning with two digits, from mid 2015 to the present;
  • labels beginning with four digits, from 2025 to the present.

Andersen's 2015 label guide says to look for a gliding door's label first at the top of the door frame. That guide names no Series, and Andersen's 100 Series label help is a video for windows, so this page cannot say exactly where the label sits on a 100 Series door. The maker label guide covers the glass logo.

The door. Andersen's product page lists standard heights of 6'8", 6'11", and 8', and standard widths of 5', 6', and 8', all as two-panel doors, with custom sizes in 1/8-inch steps. If a fixed glass panel stands beside the door, Andersen says the two-panel door can have an independent sidelight or stationary panel joined to its side.

The colors and handles. Andersen's product page lists two hardware styles, five exterior colors, and four interior colors. Its 2018 information sheet names the exterior colors: White, Sandtone, Terratone, Dark Bronze, and Black. It describes the two hardware styles:

  • Tulsa: the exterior handle matches the door's exterior color, and the interior handle is white or sandtone.
  • Afton: the same finish inside and out, in four finishes.

If you still cannot tell, Andersen says you can use its Identify My Product tool or contact Andersen to identify the door by its features.

Handing: XO or OX

Andersen hands the 100 Series from outside. X is the operating panel and O the stationary one, so a door whose operating panel is on the left from outside is XO.

For ordering, Andersen says the 100 Series insect screen is handed the same as the door, while rollers, locks, and weatherstrip are not handed. The XO or OX guide explains how to read it from inside, and the door record card is a place to write it down.

What you can check with the door in place

  1. Keep it closed and locked. Andersen recommends keeping a gliding door closed and locked when not in use, and says an unlocked door's weatherstrip may decompress and push the sliding panel slightly away from the frame.
  2. Clean the track. Andersen's method is a soft-bristle brush with warm, mild soapy water, a rinse with clean water, and letting the track dry before closing the door. It recommends this at least once a year. It says not to put lubricant on the track, because the rollers will slide instead of roll.
  3. Lubricate the rollers through the adjustment hole. Andersen applies a dry lubricant spray to the rollers through the door's adjustment hole, and says removing the panel is not required.
  4. Check the gap. Open the sliding panel slightly and look at the gap between panel and frame from top to bottom. Andersen says an uneven gap means the panel needs adjusting.
  5. Adjust the lock. Andersen's Afton and Tulsa guides give the same lock adjustment: close and lock the door. If the lock does not engage, open the door and turn the adjustment screw clockwise. If it engages too tightly, open the door and turn it counterclockwise. Andersen notes that after a roller adjustment, the latch receiver may need adjusting too.

Roller adjustment on the 100 Series. Andersen's adjustment article sends 100 Series owners to step 3 of guide 9020082, its 100 Series panel replacement guide. That step shows a roller adjustment hole behind a cap, but in that guide it is part of taking the panel out, so this site does not pass it on. The guide warns that adjustment hole caps are small parts that could be a choking hazard to young children.

Cleaning the frame and glass. The same guide says not to use abrasive cleaners or solvents on Fibrex material. Andersen also says abrasive products, alcohol-based cleaners, and power washers can damage the glass or frame. The 2018 sheet lists Low-E glass with HeatLock technology as an option, and for HeatLock glass Andersen says to use only mild soapy water.

The screen. Andersen says 100 Series screens run on two rollers at the top and two at the bottom. The screen door guide covers a screen that has come off its track.

Parts that depend on the door

Rollers. On the 100 Series, doors made from March 15, 2010 on use the same tandem roller as the 400 and 200 Series, and earlier doors use a 100 Series-only roller. To date the door, Andersen says its glass etching includes a manufacturing date: when the door was made, or when a door panel was replaced.

Locks and handles. For replacing or adjusting 100 Series lock hardware, Andersen's locking hardware article points to the Afton guide (9117142) or the Tulsa guide (9020084). It says Afton or Tulsa trim sets can be ordered from the Andersen Parts Store. The Afton guide says that when upgrading from Tulsa to Afton hardware, the panel bumper is replaced too, and warns that failing to replace it may result in injury. The mortise lock guide compares Andersen's lock documents with other makers'.

What this site leaves to a professional

  • Inspecting the rollers. Andersen says the panel must be removed to inspect them.
  • A label hidden on the panel. Andersen's label guide says that if the frame label carries no information, the Product ID is at the top of the operating panel, which has to come out.
  • Replacing a panel. Guide 9020082 warns that windows and doors can be heavy, and to use safe lifting techniques and enough people.

This site gives no steps for lifting or removing a panel. The roller repair page explains when adjustment is enough, and the alignment page covers a panel that rubs or sits crooked.

Where to take a repair

Andersen. For a product you already own, Andersen recommends reviewing its Identify Your Product tool before contacting it, and asks you to contact it while you are in front of the door. Andersen says more than 900 factory-trained service providers take part in its annual training, and its help center has a locator tool for finding one.

Replacing the door. If you are weighing repair against replacement, the repair or replace guide sets out the decision, and the Dallas replacement guide covers what the City of Dallas code says about a permit.

What this page does not cover

  • Prices. None of the Andersen documents opened gives a price for a part or for labor.
  • Warranty terms. This page does not summarize Andersen's 100 Series limited warranty.
  • Weatherstrip. Andersen's 100 Series weatherstrip article did not load on November 5, 2026.

Asking about a repair

To ask about a 100 Series door in Plano, Allen, McKinney, or Frisco, use the contact page. Give the label number if you have it, whether the door is XO or OX, and photographs of the label, the handle, and the glass logo. The operator reviews every inquiry and replies with the next step. Sending the form is not a booking.

Questions on this page

How do I know if my sliding door is an Andersen 100 Series?

Start with the label. Andersen says its Product ID label gives the Series, and that 100 Series labels vary by product type and date: some begin with SLD (2008 to 2018), some with 122 or with two digits (mid 2015 to the present), and some with four digits (2025 to the present). Andersen's general label guide says to look for a gliding door's label first at the top of the door frame. The door itself gives clues too: Andersen says 100 Series products are made of Fibrex composite material inside and out, and that the gliding door has one panel that glides and one stationary panel. If you still cannot tell, Andersen says you can use its Identify My Product tool or contact Andersen to identify the door by its features.

Which rollers fit an Andersen 100 Series gliding door?

It depends on when the door was made. Andersen says 100 Series gliding doors made from March 15, 2010 to the present use the same tandem roller as its 400 and 200 Series, and doors made before March 15, 2010 use a 100 Series-only roller. Both are ordered from the Andersen Parts Store. Andersen's glass etching includes a manufacturing date, which tells you when the door was made, or when a door panel was replaced. Andersen also says the panel must be removed to inspect the rollers; this site leaves that to a professional.

Is an Andersen 100 Series door XO or OX?

Either, depending on which side slides. Andersen hands the 100 Series from outside: X is the operating panel and O the stationary one, so a door whose operating panel is on the left from outside is XO. Andersen says the insect screen is handed the same as the door, while the rollers, locks, and weatherstrip are not handed.

Official resources

  • XO or OX? How to tell which sliding door you have

    X is the panel that slides and O the one that stays put. Andersen reads the letters left to right from outside; if your door is another make, check its maker's documents.

  • How to read a sliding door's label and find its maker

    Look in two places: the frame for a label, and the corners of the glass for an etching or a number between the panes. What you find depends on the maker, and JELD-WEN sends you to the purchase paperwork instead.

  • A printable record card for each sliding patio door

    Most of what a technician or a parts counter asks about a sliding door can be written down once, on one card, and kept with the door's paperwork.

  • Your sliding screen door keeps coming off its track or sticks: what to check

    Start with the track: Andersen says screen operating problems are often caused by dirt in the screen track. After that it is the screen's rollers or guides and how they are set. Clean the track first, then look at the rollers.

  • Replacing a patio door mortise lock: what the door makers say

    BHMA defines a mortise lock as a lock fitting a rectangular cavity in the edge of a door, and JELD-WEN's wood patio door guide describes its single-point sliding door lock as a lock assembly held by screws in the door edge. JELD-WEN and Andersen publish lock replacement steps. JELD-WEN says its repair tasks can be done by a homeowner with some mechanical aptitude, and that if you are unsure, it recommends hiring a trained service provider. Pella's manual gives no lock replacement steps, and says all service adjustments to its hinged doors should be performed by a professional.

  • Sliding patio-door roller repair

    Patio door roller repair means adjusting or replacing the wheels that carry the sliding panel's weight. It is needed when the door drags, grinds or sits crooked and a dirty or blocked track has been ruled out. Sometimes adjustment is enough; sometimes the assembly is replaced; sometimes the track or alignment was the real problem.

  • Sliding patio door alignment problems

    A panel that rubs, sits crooked, or whose latch misses the keeper is usually an adjustment question, sometimes a frame question, and never a foundation diagnosis from this site.

  • Sliding door lock and handle repair

    Many lock problems are alignment problems. The rest come down to identifying the hardware and finding out whether a match exists.

  • Repair or replace a sliding patio door?

    Most sticking doors are repaired. Some should not be. This guide gives you the questions to tell them apart, and is honest that full replacement is outside this site's referral scope.

  • Replacing a sliding patio door in Dallas: permit, glass, and energy ratings

    Dallas City Code Chapter 52 lists replacing an exterior door among the work that needs no permit, if the new door is the same size and required type, the wall framing is not changed, and the door is not part of fire-rated construction. Historic and conservation districts have their own rules. The glass in a sliding glass door falls under a federal safety standard, and ENERGY STAR sets the ratings a certified door must meet.
