Window crank

Thanks for reaching out! Your Truth casement operator reminds me of the 39-439B Encore Dual Arm Operator. The opposite handed version of this operator is part 39-438B. To confirm that this is the right replacement, carefully review and compare the dimensions below.

Dimensions for 39-439B

These operators are compatible with two different style cover and handle kits. They are the 39-375 and 39-376 folding handles with covers and the 39-451 and 39-452 non-folding handle and cover kits.

If you are looking to replace the track, you'll likely need the 39-566 SS 14-1/2" Track.
