casement operator

A contractor from Evanston, IL says:
Is your handing on casement operators 39-146 & 39-147 as looking at the window from the outside? In other words looking at the window from outside a LH would hinge on the left side and a RH on the right side.

Do the crank operators come with screws?

Thanks, Bruce

Some manufacturers go by inside looking out and some go by outside looking in. I have found in the past that some manufacturers change from series to series. The best thing to do is actually match up the original operator to photo online to figure out what side to get, left versus right.

Yes, installation screws are included with the 39-146 and 39-147 operators.
