Sliding door repair kit

Also called: roller replacement kit, patio door roller kit

Quick answer: a sliding door repair kit is a set of replacement parts for a sliding patio door, most often a pair of rollers and their screws. It only helps if the parts match your door. Fitting it means taking the panel out of the frame.

What is inside
Usually a matched pair of rollers with their screws. Some kits add a snap-on track cover or other small hardware.

Made for a make and model
Rollers differ by maker and door age, so even a kit labeled for most doors needs checking against yours.

Two people to fit it
The rollers sit inside the glass panel, so the panel has to come out: two people at least, or call a pro.
What to measure on the old roller

1234

  1. Housing length, from one end of the roller body to the other
  2. Wheel size, measured straight across the wheel
  3. Screw holes, where the adjustment and mounting screws sit
  4. Wheel edge, flat or grooved, to suit the track ridge
Measure the old roller and note its wheel edge before you buy a kit.

Using a kit: what to do

Work in this order so the panel comes out of the frame only once.

  1. Identify your door
    Find the maker’s name and match the kit to the old rollers.

    Safe to do yourself

  2. Take the panel out
    Retract the rollers, lift the panel into the top track and swing the bottom out.

    Take care: two people

  3. Swap and clean
    Fit both new rollers and clean the empty track while you can reach it.

    Safe to do yourself

  4. Rehang and adjust
    Set the panel back, then adjust until it rolls level and locks.

    Take care: two people

Fix it yourself or call a pro

  • Safe yourselfFinding the maker’s name, ordering parts, and adjusting the new rollers once the door is back in.
  • Take careTaking the panel out to swap rollers. Glass panels are heavy and tempered glass can shatter: always two people.
  • Call a proScrews that spin freely, a grooved or bent track, or parts you cannot match.

Questions people ask

Will any sliding door repair kit fit my door?

No. Rollers vary by maker, housing and wheel. Look for the maker’s name on a label on the frame or on the old roller, and take the old roller with you when you buy.

Can a repair kit fix a damaged track?

A snap-on track cover can cap a worn rail. A bent or cracked track needs fixing first: see our guide to sliding door track repair.

Is a kit worth it, or should I call a pro?

A kit suits a door with worn rollers, a sound track and two people to lift the panel. If the screws spin, the track is grooved or you cannot match the parts, call a pro.
