tilt sash window balance and shoe, ref. # 7495999

Question

Attached are photos of a balance used to replace the old coil type lift shown next to it. The balance is 33" x 9/16" x 9/16". The old shoe from the coil type lift is 1 1/4" x 17/32".

The sash weight is 42 lbs. I had a couple of extra balances left by the manufacturer but I am not sure if they were for the 3 ft. wide windows or the 42". The balance I have does not have a mfg. name but has a number 33I AI5 CMC 5.

We recognize both balance systems. The coil springs look like our Series 160 coil spring and 15-191 pivot shoe, while the channel balance looks like our Series 770. The Series 770 might have to be custom made, though. You say that your sash is 42 pounds, which indicates a special 33H stamp, but your existing balance is stamped 33I, which is for 44 pounds. Can you confirm the exact weight of your sash?
