Mercer window sash balance

Question

I can't quit figure out which 385 sash balance to buy. I can figure it all out except the weight needed. Printed on the balance is 14-3 IG5 CMC 54.

If your stamp reads 14-3, then we recommend the 1430 option. You can always weigh your sash on a scale to be 100% sure, too.
