Window Balancer 27 in.

Question

I need about 6 of these, and maybe more. It is marked 2640J and looks like in smaller print B.S.I. or something like that.

Thanks for your photos. Based on what I see here, you have either our S380-27, S385-27, or S378-27 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.
