1960s Aluminum sliding door rollers

A quick learner from USA says:
I need to replace both the rollers on the door and I think I need to also install one of the track rail covers. The rail is very worn. Can you tell me which part I need based on these pics. I do not see any brand markings on the door.

The housing is 2" x 1 3/8" and is ~11/16" wide. The roller dia. looks to be about 1 5/8" and is ~3/8" wide.

Thanks for posting! Hopefully I can help. The easiest solution might be to replace the wheel and axle only and re-use the same housing, since I don't think you'll be able to find the whole roller unit. Take a look at the 81-237 wheel and 81-310 axle kit.

As for the track cover, I'm not sure what your original track looks like, but see our 80-100, 80-102, or 80-103. If you need to replace the complete track, consider our 80-105 and 80-106. We also have videos that should help you get a better idea of how these work.

Thanks for the feedback. I have been using a system for several years where the door rides on a teflon strip laid in the track and skids are attached to the bottom of the door in place of the rollers. I removed the positioning screws from the rollers shown in the pics. I can't find them and do not remember exactly how they were assembled in the roller unit. Do you have any drawings/pictures of units where I could see how the adjustment screws look in the assembly? I assume it will be a pan head screw but does it need any washers, a lock nut, or...?

Sure, I will do my best. Looking at your photos above, it appears that the screw might be similar to our 33-104, which has a 1/4" x 20 thread count. It may also be like our 33-106, which has a 12-24 thread. It looks like the hole where the screw goes is threaded, so you shouldn't need a nut. As for a washer behind the screw head, it depends on the size of the hole on the side of the door stile, where the screw would install.
