The channels I need are 1/2" wide and 26" long with a stamp on the channels of 2540. You many products that seem to fit that description, so would like some help identifying the correct replacement parts (see pictures).

I would like to order 12 pieces once I know which one to order.

Thanks Gerry

Hello! We do have a bunch of balances that are similar, but I can narrow it down to just two choices: either our S380-26 or S385-26. The only difference between them is the depth of the bottom nylon fitting. All you have to do is measure yours and refer to our dimensions for each product to confirm the better match.
