Spiral window balance shoe

Many thanks for your correspondence. Your balance system was made by the Unique balance company. They discontinued this particular balance before they went out of business in the last century. If you are handy, you can use our  Series 500, 5/8" thick Spiral Balances with a 17-012 Screw-On Bracket at the bottom of the sash. If you are game, we will need the length of the balance tube, as well as the length of the spiral within the tube length and spiral length. Then we can instruct you on installation.

Okay. Since your old balance is 21-1/2" long with a 22.5" spiral, it looks like you can use our S500-22 Spiral Balance. This is 5/8" thick with a 22-1/2" spiral. You will also need the 17-012 bracket. To compensate for the nylon shoe, you will need to add two nylon face guides, the 67-002, on each side of the sash to prevent the sash from rocking when operating.

To summarize what you'll need to do, and the parts you'll need:

1. For your sash, you will need our S500-22 red tip balances with 17-012 balance brackets. These brackets hook on the balance spiral. To install these balances, you would drop them from the top on the side of the sash. Use 33-017 screws to attach the balance tubes at the top.

2. Now raise the sash and have someone hold it up while you attach the bottom bracket 17-012 with a 33-073 screw while the U-shape opening corrals the spiral. With your finger bring up the spiral to the bracket and attach the 75-005 tool and turn the spiral clockwise three turns and hook it to the fork of the bracket. Repeat the other side and try the sash. If sash creeps down, raise and hold up the sash and give the balances another turn or two. 

3. Finally, you will need to install the 67-002 face guide. Slide the lip between the window track and sash and screw the face guide with a 33-071 screw to the sash. 

You are welcome. Let us know how it goes, and do not hesitate to ask if you have further questions.
