Certain teed windows mount operator

Hey there,

Thanks for posting! Your window operator reminds me of the 39-221B Encore Dyad Sill Mount Operator. This does not come with a cover so you'll also need either the 39-375 (folding) or the 39-451 cover and handle kits. The link arm is attached to the sash using the 39-546 Truth Snap-Stud Bracket.

To determine if this is the correct replacement match, carefully look over the specifications and compare them.

The opposite versions of these parts can be found tagged below.
