Are constant force balances the best?
Our team is a big fan of constant force window balances. They have many advantages over other types of balances that makes us consider them the best available in today’s market.
Constant force window balances use a tape measure-like coil spring design with very low friction. The design of the coil balance makes opening and closing windows smooth, easy, and quiet. Unlike window balances with traditional springs, constant force coil balances don’t require tensioning adjustments or lubrication and they’re resistant to rust. Its simple design means fewer moving parts and the smart design means parts are less likely to break, bend, or lose tension overtime.
