Window Balance 34 3 HP Caldwell

Thanks for contacting us. I'm confident we can replace this, but your pictures only show the bottom nylon attachment. We will also need to see the top nylon attachment in order to identify the proper Series.

In the meantime, can you confirm the depth of the bottom attachment you showed us? That would help narrow it down even further. For reference, I think your show could either be our 15-004 (1-3/32" depth) or 15-005 (1" depth), I'm just not sure which. If you can confirm, that would go a long way for us finding the best replacement option.

Thank you! See our Series 380 channel balance, I think you'll find this is a good match.
