This operator appears to be a match for the 39-220B Encore Dyad Sill Mount Operator. Take a look over the specifications and compare them to confirm that this is the correct match. The opposite version of this operator is the 39-220B.
The compatible hardware and accessories can be found tagged below this thread.
