This rack type operator is a replacement for early Philips Industries window operators.  It works on many windows.  It is an excellent fit on early 1960s Serro Scotty jalousie door windows, and for the windows on 1966 to 1968 Airstreams. It will make your window operate like new again!  

It comes with a metal handle (but the original handle will fit) and the 1-1/2" link that goes between the top of the operator and the long link that connects the louvers in jalousie windows, or up to the hinge on Airstream windows.  The long link and other parts are not included.  Expect to make minor modifications to the operator parts to fit your window.

The rack is approximately 6" long.  Mounting holes are 1-3/4" on center.
