Patio Glass Door roller

Hello,

I can't make out how your roller housing is secured to the patio door rail based on your photos but take a look at the 81-295 to see if this might work for your door. 

We also offer the 81-272 roller and axle kit. However, I do see in your photo that your outside roller housing appears to be a little worn. Take a look at these options and the related videos to see if you think that either option could work for your repair. Thanks for posting.
