Replacing Rollers

Hello,

Take a look at our video below, which shows the general replacement process for sliding glass door rollers. The required steps could vary based on your door's specifications but take a look and let us know if you have any other questions. 

In your case, you'll need to lay the patio door on top of a set of saw horses or a table that is stable enough to hold the weight of the door. Next, you will need to remove the bottom rail of the door. To do this, remove the screw at each end of the door that holds the frame together. After the screws at each end are removed, use a block of wood with either a mallet or hammer to gently tap off the bottom of the door. With the bottom rail removed, you should be able to access the roller. Once you are able to remove the roller, take a look at the 81-133. I can't be sure, but I suspect that this may be the part you are looking for.

Great! Just let us know if you need anything else.
