Spiral Window Balances
Spiral window balances aid in opening windows, as well as holding windows open by utilizing a spiral-shaped rod within a tube. This rod connects to a spring, which is what provides the tension for supporting the sash. The tension is adjusted by being wound (using a tensioning tool) to match the sash it is supporting.

Block & Tackle Window Balances
Currently one of the most popular choices, block and tackle window balance systems includes a combination of two or more pulleys, a cord, and a spring. The pulleys are grouped as the “block” to reduce the load the homeowner feels. In addition, as the cord (or “tackle”) is pulled by the movement of the sash it stretches or compresses the springs, which are weighted to match the sash weight. The pulleys and springs assist with opening and closing the window. Browse block and tackle window balances, parts, and accessories.
