Custom Sash Replacement

A handy person says:
The metal from end to end is about 21" and the spring is 10-11"
and the bottom is 1" so I am looking at the 351 model. I weighed the sash at 35 lbs, and I see that this exceeds 2060 which is rated at 27-30 lbs.

The number printed on the balancer is 2090 30.

Thanks for reaching out! I've just forwarded a link with a quote for (2) of the requested S351-21 channel balances with a 2070 stamp for a sash weighing 35lbs.

You'll be able to use this link to review the quote and place the order from your online cart.

Please let me know if you have any questions.
