Spiral balance

A home owner from Albuquerque, NM says:

Aluminum windows were in the house when we bought it. No idea of the manufacturer.

Tube is 29 inches.

There was no tip on the tube.

Take a look at our S306-29 spiral balance and compare it to yours. If both balances are missing the colored tip, I would recommend weighing the window sash and following the chart under the product description to choose the correct tip color. Thank you!

I found them to be not too bad once i had it in my hand and i saw how it worked.. I had an old clip that was rusted and jammed into the window so i used a piece of 3/8soft copper tube for a/c and popped it out the bottom with some delicate force.. New ones work perfect
