Coil Balance & tilt latch

A contractor from Middletown, MD says:
Hello, & thanks for your help!

Tilt latch is marked 7H.

Coil spring 1.25" x 3.75". Lower coil is stamped 5, upper coil is stamped 6.

I combed your site, but could not find anything that looked like it would fit. Help!

Hi Tom. For your tilt latches, start by looking at our 26-263 and 26-264. Go over all the dimensions to see if these match what you need. For the Coil Balance system, your pivot shoe looks like our 15-180. This shoe is compatible with our Series 190 Coil Springs. Based on the stamps provided, you'd need our S190-540 and S190-640, which support 5 lbs and 6 lbs of weight apiece respectively. If you need a new support clip, see our 15-181. Let me know if you have any other questions.
