Hi Mal, This looks like a Paniflex door, so you can start by comparing our 23-099 center spring-loaded roller and related parts to your original hardware. It's pretty much always easiest to remove the door when replacing hardware but you may be able to get away with installing the roller in the doors current state if you have enough clearance to insert the wheel into the top track. Thanks for posting! |
