Truth Casement Operator

A quick learner from Minnesota says:
Hi,

Looking for replacements for my Truth operators. Part B is 4" from the center of the hole that connects to the window pin to the center of the hinge, and (presumably) part A is approximately 5" from the center of the hinge to the center of the crank gear.

The number "45251" is stamped on the base of the operator, and the numbers "03182004" and "1305" are printed on the base.

Welcome to Swisco. Could our 39-386 operator work in place of your current one? Look it over and let us know. If you should also need a crank hanle, our 39-114L is worth considering.

Hi Dave,

I am a bit confused. Did you mean 39-366? 39-386 operator arm is a single piece and is 2 inches longer than my existing operator.

Are the covers easily removable (and replaceable with my old set) on 39-366?

Thannks,

Mike

How about the 39-317? There is a chance this may make for a better replacement. Our link arm doesn't have an offset like yours, however, it may be worth trying and if it doesn't work, you can always swap your link arms with ours. As for the covers, they are not removable or replaceable.
