BSI Window Balances

I have several BSI window balances to replace. I did not take photos while any of them were installed (it is from another location out-of-state). The parts needed are:

BSI 26-2 (two each)
BSI 16-1 (four each)

I have included photos of the part numbers, and photos from each end of the balance (they are identical in design).

I am curious how you ship, if by UPS, or USPS. I am going back to this location in several weeks and need to coordinate shipping with my expected visit.

If I could get the cost for those balances in advance I would appreciate it, and what your shipping schedule would look like for getting these to Casa Grande, Arizona.

Thanks in advance,
Dan

Emily - I measured both balance bottom fittings and they are both 1" - so the S380 series look compatible. Based upon your recommendation, it looks like I need:

17" Series 380 Channel Balance - Product Code: S380-17

27" Series 380 Channel Balance - Product Code: S380-27

I just want to confirm that this is correct. It makes sense to me, I just want to confirm.

Thank you!
