Amesbury Series 400 5/8" Channel Block & Tackle Window Balance for Non Tilt WindowsSKU:
To Select the Correct Block and Tackle Balance:
- First, measure the length of the metal channel. Measure the metal channel only, do not include the top and bottom guides. That is your balance length. Check out our guide on measuring block and tackle window balances for more info on how to measure your balances properly.
- Next, take a look at the stamp on your balance. For this series, it will be engraved onto the back of the balance and have the form XXXX (e.g. 2130). Check out our blog to learn more about block and tackle balance stamps.
- Finally, you will select the appropriate top and bottom guides. If you need help determining what guides you need, you can view our guide on selecting your block and tackle top and bottom guides. Guides will come pre-installed from our warehouse.
- These measurements are crucial to the performance of the balance. If your balance does not measure an exact length (e.g. 22-5/8"), or if you think you have an extended travel balance, read this article and contact us before you place your order.
