Block and 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. If you need help finding the correct block and tackle window balance, you can contact uschat with us, or give us a call at 1-800-842-0974 and we'll help you find your correct replacement block and tackle window balance
