Can you help identify these

A landlord from Jersey City, NJ says:
Hello, I am a landlord in Jersey city. These parts are in windows that were installed about 10-12 years ago in a building I just purchased. Can you help identify these as I need to do repairs on numerous windows.

Hello! Check out our 15-111 shoe, 15-150D support, and finally the Series 150 coil spring. I think this hardware could work for you, but see if you agree.
A landlord from Jersey City says:
Donna, I appreciate your part sugestions and it looks like the 15-111 shoe wil work and the 15-150D support will work, bnut how do I know how many pound the series 150 coil spring should be. I'd like to order parts to expedite repairs

There should be a number etched on the spring itself, near the end that attaches to the pivot shoe. Cross-reference that number to our list of Series 190 springs. If not, give me the weight of your sash.
