Milgard Sliding Patio Door Rollers

Question

House was built in 1992 and has a Milgard sliding patio door (sliding door is on inside, with sliding screen on outside). The rollers need to be replaced, but I don't know what type to order. The glass is quite thick, and the numbers on it are:

Guardian Kingsburg CA

ANSI Z971

Safety Tempered 16CFR-120-II

Stamped inside the slider frame are the numbers: MT-1 ALI-CBA

The sliding door adjustment screw is on the very bottom end of the frame, (but it's missing).

Any idea what replacement rollers will fit this door ?

Thank you!

Bill

Hello,

The part number you provided doesn't seem to be associated with any Swisco parts. If you could show us some photos of your roller removed from the door and provide some measurements, we can go from there. Thank you!
