Replacement Operator

A quick learner from Minneapolis, MN says:
I'm looking for a replacement for a Casement Operator, Split Arm LH. Do you carry something that would work? I have attached a picture for your review.

Thanks Ed

Good morning, Ed.

Thanks for uploading your photo. Before we get started with the research, we will need to get a couple measurements from you. Take a look at the 39-317 Split-Arm Operator, you'll notice two measurements. Please give us the measurement from the center of the crank to the center of the rivet. Also, from the center of the rivet to the center of the furthest hole.

center of rivet to center furthest link hole 3-1/2

Thanks for posting. The operator in the above picture appears to be similar to the older style of the 39-171 Truth Hardware Dyad Operator, though the dimensions listed for this operator are different than the dimensions Mike asked for back in '11. Please compare the 39-171's dimensions to your existing hardware and let me know if they match up.
