ABSTRACT:
A lock for use in conjunction with a window panel slidably supported in a track of a channel member includes a stop member which is permanently and translatably secured in the track of the channel member. The stop member impinges on selected ones of the weep hole openings in the channel member to limit the sliding translation of the window panel in its track. In one embodiment the stop member includes a longitudinally extending, inverted U-shaped portion, with flanges extending laterally in opposite directions from the distal edges of the U-portion. In another embodiment, the stop member includes horizontal and vertical web portions joined edge to edge, with an oblique web portion extending from the upper edge of the vertical web portion above the horizontal web portion. A pair of tab members may extend from the oblique portion to facilitate manual positioning of the stop member in the track.
