Broken balance and mounting tab

Quick Learner from Stuart, FL

Hi, One of the balance thingys on our backdoor has broken, also the mounting tab that on the door has broken

Could these pictures help you identify the correct part?

The balance (just the metal part) is 30 inches.

A friend has shown us a similar part but without the little "wings"(2nd picture) in the second picture. He says that part will work. I can send a picture of that as well. I would as if the parts might be interchangeable.

I'm mostly interested in buying the correct parts to fix the balance in my door

Thank you

Mary

Hello, Mary. Thanks for your photos. Based on what I see here, you have either our S380-30 or S385-30, depending on the depth of the bottom shoe. That's the only difference between them. I recommend measuring your shoe and referring to our dimensions to confirm the best match.

As for your top sash guide, that'd be our 18-161.

Thanks Tom from Swisco!
our unbroken used one measures 29/32" OA. I suppose it could have started at 1" but it doesn't look like it. More like 15/16" would be believable. So I guess it's a 15-005.

Yep, that sounds about right to me. These balances undergo a lot of friction-based wear over the years, so the depth is probably going to be a hair off from what it was originally.
