Hello. Doors have two stickers on the back indicating... 1) Guardian Industries, 16CFR 1201 CAT II, Z97.1 1984, and 2) Fleetwood Aluminum Prod. Inc. Doors measure 78-1/4" (H) by 57.0" (W). Wheels -- what's left of them -- measure 1-1/2" diameter by 5/16" width. Any assistance that you can provide regarding replacement rollers will be GREATLY appreciated!
Thank you! --Robert
