Hi Folks, the existing rollers measure .750 X 3.075 and have 1.250 Dia rollers. I did order the Swisco part #
81-138. They do not fit into the channel, the rivit hinge is wader then .750. I would like to return those for the correct ones. The original rollers have a partially raised frame where the
81-138 are flat across the top or the side that meet the door. Your help will be greatly appreciated.
