These CRL Tubular Spiral Window Balances for tilt type windows will replace a metal or plastic tube balance with a sash load capacity of up to 25 pounds (11.3 kg). It will also replace the same size spiral balance with a white bushing. While this balance is packaged and sold individually, it is our recommendation that both balances in the window be replaced at the same time. 1. Check the tube diameter of the metal or plastic tube on the old balance.
How to Order Tubular Spiral Window Balances:
2. Measure the tube length from the end of the balance to the bottom of the colored nylon bushing only. Do not include the rod extension.
3. Check the color of the nylon bushing.
4. Verify that the rod extension protruding from the nylon bushing matches.
5. Match tube diameter, tube length, nylon bushing color against the information shown next to the catalog number. If all agree, and the rod extension matches one in the photo, then this is the correct balance.
