Installing window crank handle

Question

I ordered the crank handle 39-114L to go with an angle drive that we bought a few weeks ago from Swisco. But the crank handle has no set screw, so I have no idea how it is supposed to stay on? This is for a skylight in the ceiling, so it falls off w/out a screw. Thanks.

The 39-114L are a newer style handle which "snaps" on to the operator spline with out the need of a set screw. These handles work with Truth hardware. If your operator made by Truth, with a spline size of 11/32", it should work. If it's not Truth, however, then there may be issues. Let me know!
