SWISCO - The Replacement Hardware Authority

Window hardware inquiry

A quick learner from Ann Arbor says:
Should the total weight of the springs match the window weight? I purchased 2 152-3 coil springs to replace ones with a CL stamp on the end. The window weighs approx 26lbs, should I get 4 6lb ones?

Thanks for posting. Yes, in the case of coil springs specifically, you want to add up the strength of each individual spring. If your sash is 26 pounds, then four 6 pound springs should do it.
