What does 39-337 fit?

A home owner from USA says:

I have a skylight window with a crank handle. Saw your 2" Crank Handle Extension, 11/32"
Product Code: 39-337. Does this product fit any type of crank handle? My crank handle is like your Crank Handle, 11/32" Product Code: 39-114L. Also, do you sell the pole ( 10+ feet long) that would attach to your Crank Handle Extension. Thank you.

As long as your spline size is 11/32", then the 39-337 should work for you. It only works for handles and operators with this spline size. I'm afraid we do not sell extension poles.
