Does Truth 31272 match 39-031?

Vetter casement window, about 22 years old, numbers on parts are 20610
31272,31538. Any thought on a suitable replacement?

The long arm is 10 3/4" and the short one is 4 7/16. So it looks like 39-031.

Thanks!

Hello! I agree, the 39-031 and 39-032 look like good matches, especially if all of our dimensions are the same. The numbers you gave us are often related to these parts, but they're also related to a few others, too. In situations like this it's best to rely on measurements rather than stamps, which can sometimes be unreliable.

Thanks very much. Which handles do you sell that fit your 39-031? Is there any other hardware, such as clips that you recommend I purchase for a replacement?

Sure, we recommend the 39-114L for this operator. As for other parts you may need, it would depend on what's broken on your window. Assuming the operator is the only thing that is broken I see no reason why you can't re-use your current hardware.
