I am in need of two 3030 BSI window balancers. The originals in the pictures I've attached are like 30 years old
Hello,
Take a look and compare the specifications of the S377-31 channel balance to yours. Your stamp code would correspond to the 3030 strength option shown on the balance product page.
If needed, we also carry the 16-023 Pan Am take-out clip. Take a look and compare the dimensions below to yours. Thank you!
That is a bit strange since this type of balance stamped with 3030 would generally have a 31" long metal channel, not including the end fittings. It's possible that someone may have cut them down to size and used a different bottom-fitting for some reason.
If these balances have worked well up to this point, we can supply replacement 30" balances with the same specifications but we will need to know the depth of the bottom fitting and the exact weight of the window sash to determine the corresponding strength option for your new balances.
Thanks for getting back to us. It sounds like you would need the S377-30 with 2930 strength options to support a sash between 16-23 lbs. With that being said, we do not carry a non-winged bottom fitting with a depth of 1-3/32". Our closest options would be the non-winged (1") 15-002, (1-1/8") 15-001, or the winged (1-3/32") 15-004 bottom fittings.
Take a look to see if you'd like to try using balances with one of these bottom fittings attached, which we can provide through a custom order. Keep in mind that custom balances can not be returned for a refund, so we like to cover all of our bases.
You got it! I'll email you a purchase link and price quote right now that will let you add 2 of these balances to your cart. These will be custom assembled as per the above specifications.
Please note that the 16-023 take out clip will not be included with this link, so don't forget to add that to your cart, too. Once you've added everything to your cart, custom and non-custom, you can checkout as normal with everything all together.
Please feel free to reach out if you had any other questions.
You're very welcome, you as well! Please don't hesitate you reach out if we can be of any further assistance.
