Replacement balance.

Thanks for writing in. This old arrow balance isn't made anymore, but it can be replaced by one of our Series 775 Channel Balances. Measure the length of the old rod to know what length balance you need. Measure the size of the wedge shoe to know what size wedge you need (1" or 1-1/4"). Finally, weigh your window sash, and match that exact weight with one of the weight ranges listed alongside each stamp option on the product page. Let me know if you have any questions.
