I need to replace the spiral balances on my window. It currently has 2 pairs of spiral balances installed per side (2 per side, 4 total). The window weighs 61.8 lbs. The tube is plastic at 7/16" dia. by 29" long. Will a 3/8" work? And what spiral balance would you recommend?

Hello,
Unfortunately, we do not carry spiral balances with 7/16" diameter tubes. The 3/8" diameter S900-29 balances would be our best options but they are designed to use one on each side. We have seen them used with two on each side as shown in your photos but you'll need to double the strength options.

How to measure the tube length of the S900 spiral balance.
For example, the yellow tip S900-29 balances are calibrated to support between 24-34 pounds using two balances. Using four would increase the weight range to 28-68 pounds. If you decide to give these balances a try and run into any trouble, our return policy can be found here.
