Replacement window operator

Question

Casement window mfg is Silver Line. 17 yrs old. The hole in window (picture 4)is 3 5/8" wide. The arm when straight out is 8 1/2" from base to mounting hole. The long arm is 5" from joint to hole. The short arm is approx. 3 5/8" from base to joint. I tried Swisco part number 39-171, Truth Hardware Dyad Operator. It would not fit through the window hole. So which window operator do I need?

I'm afraid your operator is discontinued and no longer made. You'll need to use something like our 39-315 and 39-316 as substitutes, along with a new sash brackets like our 39-545 and 39-546. The trouble is that you'll also run into the issue of the base not fitting in the slot. You will have to alter the hole in the sill to accept the new style base.

Even after all that, there's still no guarantee that our hardware will work. I would recommend having a local professional come out and look at your windows for a second opinion.
