Bottom roller for sliding glass door

Hello,

The 81-095 roller comes to mind but the dimensions would be the determining factor. Take a look and compare the specifications below to yours.

If you'd prefer to replace the wheels and reuse the original housing, you're welcome to look through our selection here, depending on the size you need. It does look like your roller is showing some signs of wear, so I would personally opt to replace the entire roller if possible, but it's ultimately up to you. Thanks for posting!
