Rplacement rollers for Sliding glass patio door

Hello,

I personally think that the 81-081 might be a better match for your roller. It has the same 1-1/4" diameter wheel, while the housing measures 1-3/16" tall by 3/4" wide. It also has locking dimples near the bottom of the housing similar to the one in your photos. 

Take a look and compare the specifications to your roller to confirm if it will fit into your door rail. We've also related a few videos to assist you. Thanks for posting.

Just to clarify, the part that we recommended is the 81-081 roller assembly, though you are welcome to try the 81-046 as well. If you'd like to give one or both a try and run into any problems, our return policy can be found here.
