I have old Alcan windows. Single tilt with broken channel balances. on back of channel it says: UNIQUE 10/31/96 15-0(?)-30

The channel is 16"metal end to metal end and true 1/2 " deep x 1/2" wide. there was no nylon guide riveted to top and the bottom has plastic piece riveted flush to bottom. it is 1/2"wide and 5/6" high with a hole in the bottom that the string passed through.

can you help?

I dont know how to attach photos to this. I know how to email pictures if there is an email address you can look at though

Thankyou, Marsha

We appreciate your photos, Marsha. Unfortunately, Unique balance company has gone out of business. For your balances, you should be able to go with our S770-16 balance with a 16C option which holds a sash weight of 10-16 pounds. Look it over and see if this could work for you.

Thankyou a thousand times over. the 770 balance you suggested was perfect. You are BRILLIANT!!! Now I am ordering more to fix the other broken windows of the same size and will attempt the larger windows after that.

you amazingly got me the channel balances I needed for my small windows. They work great now. Next I have 2 larger alcan windows. Single hung. the old channel balances are 28" long. True 1/2" deep channel by true 1/2" wide. Again,looking just like the other small windows they have no nylon guide on the top and a hard plastic piece riveted on the bottom that the string passes through. the numbers stamped on the back of the channel : UNIQUE 27-D-40
Can you help me out with these puppies?

If it has the same attachments and is just a different length and stamp, then you can look at S770-28 with a "28D" stamp option.
