Hello, the coil has "740" stamped on the coil just below the screw. I need 2 of them. Can you help me?
Regards,
Dan

Sure thing, Dan. I'm pretty confident we can supply this. Before I recommend anything, can you tell me how thick the spring is? Can you also flip the shoe over and show me its face?

The spring is 1/2 inch wide. I've flipped the shoe over for you to see. This is from a window that is 32 inches wide by 34 inches high. Thank you for your assistance.

Thank you! These pictures are a huge help. It looks like you have an older version of our 15-180 shoe, which means your spring would be a match for our Series 190 (also 1/2" thick). I am very confident that this spring will work for you.

Thank you, Tom. I'll order them and let you know how it turns out. Thanks again.
