SWISCO - The Replacement Hardware Authority

Casement Operator

A contractor from New Jersey says:
I have a 13 1/2 in operator to replace. Your 39-399 looks close. The one I have is surface mounted and mounted with two machine screws to the frame. Does this operator have the two threaded holes for the frame mounting? Also. What are the hole spacing dimensions? There is no diagram with the measurements.

Dave from SWISCO responded:
I took a look at our 39-399 operator and it seem to have the two mounting holes you need. They appear to be 4" on center. Could this work for you? Also check to see if you need the 39-541 track slide and 39-114L handle, though you could always reuse your old ones.
