Hi -
I'm trying to find the attached Window coil balance that will hold a combined 40lbs. The balance is 7/8"w and has two screws. I'm not sure but I think it has two coils. I'd like to get two to test (l and r) and if they're correct I'll need 8-10 more. I can't tell if there are any markings that would help me further identify these. Please let me know if you have them or if you can get them. Thanks.
Aaron
