Replacement coil balance.

Question

Markings on the spring are faded but I can see 33" and a marking below that ends with what looks like 23208.

Thanks for posting. The pivot shoe resembles our 15-111, which means you need either our Series 160 1/2" thick or Series 165 3/8" thick Coil Balances. Please measure the thickness of your old coil springs so we can confirm what you're working with. In either case you'll need to choose new spring weights. The stamps on your old springs aren't entirely clear to me, so I'd like you to weigh the window sash these coil balances support. Give me that exact weight and we can work out what you need.
