Single Hung Block & Tackle Balancer

A quick learner from Middletown, CT 06457 says:
ID Mark on 29" Balancer = 2830 ; B3N
Can you please match this up with one of your balancers with channel balance top and shoe installed? Not sure if any of those numbers indicate the weight of the sash? Need a strength that will allow a small, elderly woman to open the lower window sash.....please advise the best one. Thanks. Dan.

Thanks for posting. Sounds like you have a 29" block & tackle balance with a stamp option of 2830. I'm afraid that's all I can tell based on your information, though. Now you just need to pick out the top and bottom fittings in order to determine the Series.

I recommend that you look at our Channel Balance Home Page and follow the steps in order to find the Series that best matches what you have.
