ABSTRACT:
A lock is disclosed herein for sliding panels such as doors or windows, which prevents the panel from being moved or removed from its mounting rail or slide. In one version, the lock includes a base mount secured to the rail or slide having a laterally movable pin latch member adapted to be inserted through an opening in the frame of the panel. The pin or latch member includes a key at its tip receivable through an indexed slot of the opening so that when turned, the pin is prevented from being withdrawn. A retaining screw selectively holds the pin to the mount. The other version includes an elongated sleeve fixed to a sill and having an open-ended bore for insertably receiving a rod carried on the panel frame. The rod has a plurality of spaced-apart grooves for receiving the end of a retaining pin threadably carried on the sleeve to prevent removal of the rod from the sleeve.
