28D USB Channel Balance

Question

We are needing to purchase 6 of these window channel balances.

This looks like either an S380-29 or S385-29. The only difference between these two balances is the 'depth' of the bottom nylon shoe, so compare both with your old hardware to see what matches best. Your stamp code of 28D should conform to our stamp option of 2840, which is for a window sash in the weight range of 23 through 28 lbs.
