Replacement Part Assistance

A professional from South Florida says:

I am looking to replace the wheels on my sliding glass door and was wondering if you could let me know if the parts I have picked out would be correct to use before I place the order. For the axle I have picked the roller replacement axle product code 81-304 and the Nylon concave BB wheel product code 81-236. Attached are photos of the patio door roller that I would be needing to put the wheels on with the measurements included.

Thank You for your time and assistance,
Enrique

Good morning, Enrique.

Yes, I think the 81-236 Nylon Roller and the 81-304 Axle will work for you. Personally, I like to use the 81-225 Steel Roller on glass doors, and I like to replace the complete housing, yours of which looks similar to the 81-020 Sliding Door Roller.

My sliding glass door currently uses a Barton-Kramer 458 single wheel roller assembly. Does one of your double wheel roller assembly models correspond to that model? Thanks.

Thanks for posting! I have placed you into an existing discussion regarding this handle. As you can see, Donna has suggested our 81-020 Sliding Door Roller. Take a look and see if you agree.
