SWISCO - The Replacement Hardware Authority

Locking and Guiding Member for Awning Windows

A home owner from St. Pete, FL says:
The only identifiable numbers on this black plastic locking and guiding member for my awning window is "PAT NO 3444648". I've included a pic of one part that is intact on the window and a pic of the drawing from the patent I found online. Any idea what part would replace this?

I need 2 in the same configuration as the picture (right hand side looking in from the outside). Just the black plastic pieces seem to be breaking (in addition to the operators I send another email about just before this one)

argh the joys of home ownership!! Thank you in advance for your help, I'd like to fix this without paying an arm and a leg in needless labor or the cost of my first born to replace these old Florida windows!

Thanks for posting. Please see SWISCO part number 39-539, Vent Hinge Pair. Compare the measurements to see if this can work as a replacement.
