Channel balance and pivot bar

Look over the three tilt bars that we placed on the right side of the page and compare them to an intact pivot bar, maybe from another window. Can you use one?

The balance will be our S770-25 tilt balance. The sash weight for a stamp of 2500 *may* be 11-17 lbs, but you need to check that by weighing the sash. If it does fall in that range, use our spring weight "25B."
