Different dimension for my roller vs item 81-156




Hey there,
Thanks for reaching out! I'm afraid we do not have a direct replacement match for your existing roller and I'm not sure that it is available any longer. Unfortunately, I didn't have much luck finding it with any of our suppliers.
I rechecked the measurements of the 81-156 and they are correct; especially the 1-1/2" height. That being said, my first suggestion would be to check inside the roller door "cavity" to see if you have the clearance for the height.
If that is not an option, my second suggestion would be to see if you could use some washers to bring down the housing without interfering with the clearance at the bottom of the door.
My third (and final) suggestion would be to take a look at the 81-266 1-1/4" dia Roller And Axle Kit. If your roller housing is in good working order then replacing the wheels might be the way to go. Take a look at the video tutorial below for reference.
