The Two Hole Wedgeless Cam Handle 1-1/4" is constructed of die cast metal and the flap is plastic. Hinged flap rolls down and locks the window shut. We find this window handle is used a lot in the western states on residential windows. The older version had a 1-3/8" hole spacing, but the new one has 1-1/4" hole spacing.
Sometimes we find the number R1 and CAN on this handle
