length of operator arm?

I need a single arm operator for a casement window, the original is missing and it appears your 39-254 operator would work. The window is 21" wide by 33" high and the track the operator fits into is 13 7/8 long. It's a vinyl window so the operator has to fit in a slot in the frame that is 3 3/4" wide by 1/2" tall. Will this operator work or do I need one with a longer arm? Thanks

I'm not sure. You say your existing track is 13-7/8" long. Operators similar to the 39-254 take the 39-505 type track, which only come in 11-3/8" lengths. If possible, please send us some photos of your casement window along with the track to help us identify the hardware you need to fix your window. Also do you have any other casement windows in the house that take the same type operator?
