Need a Tilt Channel Balance

A handy person from Sarasota Florida says:
I am wanting to buy replacement channel balances for my tilt windows. My current balances are marked Unique Balance 27F. However, my unit measures 28 inches long and 1/2 inch wide.

Your S770-28 28" Series 7 looks like my unit. Is this the correct balance to replace with mine?

Thanks for posting, Don. Without seeing a few pictures of the ends of your balance, I cannot confirm if you have our Series 770 channel balance. As for the stamp, you could consider our 28F option, but I don't know if that is what you need. You should weigh your window sash to be absolutely sure.

The 28F option can carry a window sash weight range of 32 through 36 pounds. What is the weight of your sash? Does it fit in that range? If not, let me know what the weight is and I'll find you the appropriate stamp.

Thanks for the help Tom. I attached a copy of pictures I took of one of my broken balances. Also, I took a shot at weighing my window sash and I came up with 37 lbs. I consider this an approximate number.

Thanks for posting. If your window sash does, indeed, weigh 37 pounds, then your balance will have to be custom made with the 28G stamp, which carries 36 through 40 pounds. To begin, take a look at this Custom Channel Balance Order Form that I have started for you and fill out the rest of the information. One of our representatives will contact you shortly thereafter.
