Woodco Casement Operator

This is a Woodco casement operator (see photos & diagram). The dimensions are as follows:

Arm length: 11"
Length: 4"
Length at bottom: 3 3/4"
Height: 2 3/4"
Distance between top two screws: 3"

It has a nylon roller. There are four screw holes.
I need the operator with the arm that goes to the right (the opposite side).

Please let me know if you have this or a similar one.

Thank you.
Alan

Hi Dave,
Thanks for your prompt response. Yes, the 39-013 looks to be very close. Does it matter that the arm is 2 1/2" longer than the original? If not, then I think I can go ahead an order it. (Actually it would be 39-014.) Please let me know at your earliest convenience.
Again, my thanks.
Alan

I just did some measuring, and it looks like 39-533 will be the best choice. I'll order that one with 39-014. I'm delighted that you have replacement parts that will work. I'll be sure to spread the word about your company. Thanks for all your help, Dave.

l have exactly the same operator LH with 11" arm. The crank says Woodco and the dimensions are identical.
l will try the catalog numbers you suggested and hope they work. Thanks for the help!
