ABSTRACT:
The apparatus includes a lock unit having dual eccentrics that are spring biased toward an opposing planar support flange. The lock unit is mounted so that a selected sidewall of a conventional sliding panel track is squeezed between the eccentrics and the support flange by the force of the spring. Slide stops extend from the support flange into the operative area of the track to prevent horizontal sliding movement of the panel. The apparatus further includes a lift stop which may be used in conjunction with the lock unit to prevent the sliding panel from being lifted clear of the lower track. It comprises a flat spring having a bias toward assuming a U-shaped configuration. The spring legs are spread so that the spring can be inserted into the upper panel track above the panel.
