Truth brand

Thanks for posting! The window operator you have here is no longer available but our 39-172 Truth Hardware Dyad Operator should work to replace it. The arm is a bit longer but it shouldn't impede the function of the window. 

The compatible handles have been tagged below, along with the opposite handed version of this operator.

Dimensions for 39-172

If the operator cannot be installed as it, we have a solution, but it would require using a drill and the 62-014B Rivet.
