Door track/rollers
I need the track actually as well. It is broken
It is an 8ft piece
There is actually no track on our door. What was in there was the track cover they installed prior to us moving in.
Thanks for reaching out to us! Your sliding glass door roller reminds me of the 81-182 SS Patio Door Tandem Roller. To confirm that this is the correct replacement, carefully look over the dimensions and compare them.
You may able to use our 80-106 6' Sliding Glass Door Track but that will depend on how the existing track is installed. If it can be removed, this can be installed in place of it. This track is only available in a 6ft length, so you'd need to purchase (2) and cut them to sit flush in the space. Take a look at the video tutorial tagged below for an idea on how to install it.
Another option may also be the 80-102 track cover. However, it will not work if there is extensive damage to your existing track. This is also only available in a 6ft length.
