Nash engineering roller

This is tough. The Nash company has been out of business since the 70's, and this particular door was discontinued in the 60's. You will need to keep the housing and just replace the wheel. Your wheel looks like our 81-116 1-3/4" diameter wheel. We also have the 81-236 1-1/2" diameter wheel, as well. Please compare your part to our options.

Hello,

Unfortunately, your roller assembly has been discontinued for quite some time as mentioned in this thread above. We did carry a 1-3/4" diameter wheel when this thread was started in 2017 but, unfortunately, that part was discontinued as well. We apologize for the inconvenience.
