77ip


77ip balances are an inverted block and tackle balance designed for residential tilt applications. It is designed to handle sash weights of up to 45lbs. This balance travels with the sash, making it a logical choice for replacement or new construction window applications requiring full sash opening. Since the balance is hidden from view, jamb pocket covers are eliminated for cost savings. Smooth and easy sash operation, with long cycle life, is a standard feature with this proven product.
