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 track includes a generally tubular portion extending the length thereof and the stop member includes a generally U-shaped lower portion, with the distal end of the U-shaped portion slidably disposed in the tubular track portion. The stop member includes a web portion extending upwardly from the U-shaped portion, and a top panel extending orthogonally from the upper end of the web. The stop member may be pivoted about the portion engaged in the tubular part of the track to increase the frictional engagement therewith and prevent translation of the stop member. The top panel of the stop member includes obliquely extending edges which are engaged by the sliding window panel to rotate the stop member into the locked position.
