Tilt Window Coil

A landlord from Denver, CO says:
I am looking for replacement parts for my windows of the Apartment Building I do the maintenance on.

The windows are double pane 41 x 31.5 and weigh approximately 20-30 pounds

The coils have the letters EL imprinted on them and are 1/2 inch wide.

The whole part is 3 1/2 inches tall from coil to base.

The base is 1 1/4 inch wide

The pin is 3 1/8 inch long

Thank you.

Thank you for the clear pictures and the detailed information! I recommend you start by looking at our 15-175 pivot shoe and Series 152 coil spring. Let me know how well our hardware matches yours!
