Patio Door Track Cover (80-103)

I've been putting these covers on my glass patio door track for the last 6-7 years and find that they last about a year or 2 before they begin to flay and have to be replaced.

What can be done (if anything)to keep this from happening?

Tom:
Will take your advice and inspect the rollers. If they are worn/frozen, I'll remove one and take a .jpg of it and e-mail it to you. I trust you'll have the replacements that may be needed.

Thanks for your help.

I've replaced tandem rollers in doors where all 4 rollers are are worn all the way to the ball bearings with zero damage to the SS cap. If they are flattening out it is probably because the rail that the door is sitting on is too short to support it - or missing large chunks. The rail must be at least as tall as the SS cap. Short dips or gaps are OK. The 1/4" cap is not meant to support the door's weight. The taller SS caps are much stronger, but are too tall for some applications.

Took your advice. I removed the door and examined the rollers. They both spin free but are wobbly. Seems like the wheel bearings have too much "play," probably caused by normal wear and tear.

Do you think the roller "wobble" could cause the track cap to flay over time?

BYW, as best as I can tell, the roller type is most likely 81-112 (your code).

Your reply is appreciated.
