A housing for installation in a window sash having a slot defining a pair of opposed edges, the housing comprising:

• a) opposed side walls each having upper and lower edges;
• b) a top wall extending along and beyond the upper edges of the opposed side walls to define a flange;
• and
• c) a plurality of deflectable retainers projecting angularly away from the lower edge of each side wall, said retainers together extending along a substantial portion of the length thereof, each retainer defining an upper engagement end, such that a gap is provided between the upper engagement end of each retainer and an undersurface of the flange to accommodate reception of the opposed edges of the slot upon inward deflection of the retainers during installation, wherein a portion of each said retainer that is adjacent to the upper engagement end is beveled.
