2002 Acorn tilt window coil balance needed

Handy Person from Minneapolis, MN
The coil balance part was broken when the 2002 Acorn tilt window was raised to the top. The part has been misplaced or thrown away but I think the stamp says... 5.0 3S

Time-sensitive. I rent and need to fix the window before May 31, 2022, move-out date. If possible, please prioritize my order.

Hello!

This looks like a match for our 15-111 shoe which uses the Series 160 coil springs. Look this over and see if you agree.

Yes, I agree and will order a pair of each. Can you tell from the stamp on the coil in the second picture what sash weight I should order? Thank you.

Judging from your stamp code you might need a 5 pound coil weight but the Series 160 doesn't have an even 5 pound weight as an option. With that said, we suggest weighing the sash and dividing its weight by the number of coils on both sides of the window to determine the correct strength option.
