Block and tackle channel balance

Thanks for posting. We may be able to help, but that stamp is not an identifier, it just signifies the strength of the balance. We will need pictures of the attachments at either end of the metal channel, as well as the length of the metal channel. See the video below. We'll do our best to assist you from there.

Thanks! This looks to be a match for our Series 795 tilt window channel balance. Look it over and see if you agree, or let me know if you had any questions. A few key details to note are that the shoe on ours is 1-1/4" wide, and our balance installs at the top of the window with a screw, not a hook.

If yours differs in any way, come back here and let me know how. I'm happy to explore any alterations you may need.

Great, thanks for checking. If your balance attaches at the top with a screw then our Series 795 balance should work perfectly fine as-is. 

All orders may be placed on our site at your convenience. Please feel free to reach out if you had any other questions and I'd be happy to assist you!

Hello! I'll do my best to answer your questions in order.

• Yes, the Series 795 comes with a 1-1/4" wide T lock shoe pre-attached. These balances are fully assembled and ready to install out of the box.
• A 30" balance will not replace a 17" balance, but we do sell a 17" option for this series. See our S795-17.
• A stamp of "16 7 B" is a little odd, admittedly. I think it might just be old fashioned. My gut tells me that our 17C option will work, but to play it safe you should weigh your sash on a scale to verify. We have a weight chart on the S795-17 store page that tells you exactly how much weight each stamp supports. As long as your sash weight falls in that range, you should be A-OK

Please let me know if we can be of any further assistance.
