CHANNEL BALANCE FOR OLD DOUBLE HUNG WOOD WINDOWS

Hello,

We'd be happy to help but, unfortunately, your assembly does not look like a match to the S800 channel balance. If you could show us an undamaged balance removed from one of your windows, including detailed photos of both ends and any numbers stamped on the channel, we can go from there. Thank you. 

It sounds like you are describing aluminum jamb liners with a balance system behind the track. Unfortunately, this type of system is no longer made. I believe your best bet would be to remove one jamb liner and take it to a local millwork to have them fit you with new-style jamb liners. 

If you want to keep your jamb liners, you could try using our 3/8" thick S400 spiral balances with the 17-031 brackets. It might work, but it will be difficult to install. With the bottom sash held up, you would slide the balance tube up into the jamb liner and attach it at the top of the track with a 33-012 screw. The spiral will twist down to the sill, so you'll need to bring the spiral up to meet the 17-031 bracket attached to the bottom of the sash. 

Then, hook the 75-005 charging tool to the spiral and give the spiral about three turns clockwise. You will feel the tension build and then you can hook it to the 17-031 bracket. Do the same on the other side and try the sash. If the creeps down, give the spiral another turn. Review these parts to see if you might be able to adapt them to work for your window repair. 

Unfortunately, we cannot supply samples of our balances but you are welcome to purchase the S400 spiral balances that we mentioned on January 16th to see if you might be able to adapt it to work for your repair, although we can't make any guarantees. 

Great, we appreciate your business and look forward to hearing how the repair works out for you. 

That's great to hear! Since the balances that you used are stock parts, you are welcome to order more of the S400-20, S400-16, S400-22, and S400-24 spiral balances directly on our website.
