26E Series 770 balance

A contractor from New Jersey says:
I am trying to replace a balance from a silverline window. it is similar to the S770, is 26 inches long, but is marked with 26E and 8SI embossed on the channel. Your web page only shows A, B, C and D available. Is an E available or will a D work as a replacement?

Tom from SWISCO responded:
We can custom make a balance with the 26E stamp, but before we do I'd like you to confirm the weight of your sash. Two balances with the 26E option can carry a window sash weight of 26 through 30 pounds.

If your sash weight falls within that range, then check out this Custom Channel Balance Request Form I've started for you based on your specifications and fill out the blank fields. One of our representatives will get back to you with a price quote and an item to add to your cart.
