Window Balancers

Question

Good afternoon we purchased our house in 2009 and we are looking to replace the block and tackle type window balancer which is broken in one of our windows. Please see the attached pictures. When I measured the metal piece, it was 29 inches. We looking to purchase two new window balances.

Thanks for posting. Is the metal channel 1/2" wide? If so, this is most likely either an S380-29 or S385-29. The only difference between these two channel balances is the 'depth' of the bottom nylon shoe, or 'heel-to-toe' measurement. See the diagram below. Measure your old balance's shoe depth to see what matches best. In either case for a stamp option choose 2860.
