Single arm operator for 39-375

The 39-375 can work with various Truth operators, though I'm not sure which one can work for you. If you were to take a couple pictures of your operator removed from the window we can recommend something.

Thank you! No, I'm afraid the 39-375 will not work for you. Your operator's cover is actually built into the part itself and cannot be replaced. Our 39-205 should be able to work for you though. It's a folding crank handle with an 11/32" spline.

The 39-375 is used on the Truth "Encore" Tango operator. These are a newer style operator made by Truth that have a different type of track and hardware than what your operator uses. You will not be able to use it in your window.

You have an older model which does not take a nesting cover. I'm actually shocked the 39-205 did not work for you. It was made for operators just like yours. Do you have a spline size different than 11/32"?

Ah, I understand now. This is a pretty common problem that a lot of older casement windows encounter when new shutters have been installed. It's frustrating, but unless the shutters were designed with that specific window in mind your options will be very limited. Changing to the 39-375 isn't just a matter of getting a new track, but you'd also have to alter the sill and trim. The only other solution that comes to mind is our 11/32" 39-102 T-handle. This may give you the clearance you need.
