Claims22
A housing for installation in a window frame having a window sash with a notch defining a pair of opposed edges, the housing comprising:
- side walls each having rearward and forward ends;
- a top wall extending beyond the side walls to define a flange extending along the side wall toward the rearward and forward ends of the side walls;
- and
- retainers at the side walls and spaced from the flange for receiving the edges therebetween, each retainer having a rearward end located toward the rearward end of the side wall, a forward end located toward the forward end of the side wall, and an outer side facing away from the side wall, wherein each retainer is beveled at its rearward end such that the rearward end of the retainer slopes outwardly in a direction toward the forward end of the retainer from the side wall to the outer side of the retainer to define a rearward camming surface.
