SWISCO - The Replacement Hardware Authority

Is the S777-28 the proper replacement for this channel balancer? It is stamped 28D on the broken balancer.

A handy person from Windermere, FL says:
Hello,
One of my single hung sliding window channel balancers broke at the spring holding pin and nylon chord. The window weighs 24 lb and the balancer is approximately 28" long. The broken balancer is stamped with "28D". I assume your model S770-28 would do the trick, but the ends on my balancer look a little different than what is pictured on your website. I would like to verify it is the correct balancer prior to ordering four balancers.
Thanks,

Pedro

Hey, Pedro. Please see our Series 380 channel balance. I think this is our best match for your hardware.
