Hi, I have a dual roller for a Kinco insulated door. It's stamped DISCO 2191 and it replaced the original roller once before. I am sure that your best match is the
81-153, the question is my 3 1/8x 11/16 part is pinched-in where the press fit pin through the wheels assembly attaches to the mounting 3 1/8 x 11/16 part. This allows the wheel assembly pin through the 3 1/8 x 11/16 to be no wider than the 11/16 width. I bought a roller replacement at my local parts dealer, the problem is that the mounting pin is a rivet and the heads of the rivet are slightly wider than 11/16 and it binds up on the inside of the sgd bottom rail and I can't adjust the up and down of the wheels. Your
81-153 looks the same (riveted)as the one I bought that does not work. Does the 81-53 width exceed the 11/16 at all.where the pin (rivet) is ? The picture looks like it does. Any suggestions how to still be able to use the
81-153 if it is ? thanks alot.
