Rollers for sliding door

A home owner from Framingham, MA says:

We have a white vinyl/glass sliding door to our deck that has the following inscription on the glass:

PPG Herculite K
Tempered Safety Glass
Can/CGSB 12.1 M
16 CFR 1201 C11
ANSI Z 97.1 1984 1/8U
SGCC 250

There is no mention/label indicating manufacturer of the door anywhere. The door tracks are clean and it slides smoothly, but it "rocks" in its frame. Hence, it will not lock completely in spite of turning the latch all the way (engaged in the top and bottom locks on the door jamb). Can you please tell us what specific rollers we need for it based on the attached pictures?

Thanks a lot!

Thanks for posting. It's very difficult to identify what roller you need without actually seeing it. Based on your description of the problem, you could consider adjusting your rollers. Try doing that before you replace them, just in case. The adjusting screw should be on the face of the bottom rail. If that doesn't work, I'd like to see your rollers removed from the door. You could consider our 81-018 as a possible match, but this is just an educated guess.

Thanks for your prompt reply. We were able to remove the door and check on the rollers. I need the reverse mount 1-1/4" dia double-wheel rollers (81-141). The existing rollers are OK, but even with the door fully raised in its track, the deadbolt lock does not fully engage in both the top AND bottom keepers (please see 1st and last pic above). I believe we need a better internal lock as new rollers will not help. Any recommendations?

It appears that you have a multi-point handle, which locks at the top and bottom of the door track. First off, see if adjusting the rollers will help you lock the door. If not, see if you can adjust the lock in the door. Some multi-point locks can be adjusted in such a way.
