Can I replace crank handle with t-crank on Pella older windows?
We've got Pella windows circa about 1968, with crank handles that have a 3/8" 11 teeth spline. I've seen small t-crank handles that are supposed to be able to replace the large cranks -- do they work even with the older windows?
Also, does anyone know if you have to turn them like a faucet, or do they "ratchet" back and forth to make cranking easier?
Thanks so much.
