Howdy! I need to replace a counterbalance for an ALENCO single hung tilt window. The dimensions are the 9/16" wide (1/2") non-ribbed channel. Overall length is 26". Please see pictures attached.

Let me know what you think!

Thank you. Jeff D

This looks a lot like our Series 770 channel balance. Take a look and see what you think. You will need the stamp from the old balance to determine the best option. As for the shoe, see our 15-129. This may be a good match but I recommend going over our dimensions to confirm.

Thanks for the reply. Just exactly what do you mean by the "stamp"? Is that some kind of part number embossed on the piece somewhere?

Yep! A stamp is any kind of numbers either stamped on or engraved into the balance. It's indicative of the spring strength rating. You can see a list of stamp options we have on every Series 770 store page and how much weight each one can support.

Thanks, I will take a look at the balance to see if I can find any identifying markings. Will let you know if I cannot figure it out. Thanks for the help!

Here is a picture of the Stamp. Looks to be: g C2540 Can you cross reference your part number? Thanks!

Thanks! That stamp is a little atypical. I think your best bet is to weigh your sash on a scale to confirm the best option.
