This roller looks just like part #
81-138 from your website. The only difference I notice is that my wheels measure 1-1/4" (outside diameter) and the wheels on the listed part are 1-1/8". My roller is marked "DELMAR HARDWARE TORONTO." Can you help me locate the correct replacement part? I'd like to order two rollers. Thank you!

Is the wheel diameter measurement taken on the outside of the wheel, or on the smaller, concave inside?
Also, perhaps the 1-1/8" wheel will be big enough considering the adjustment built in to the roller.
