ABSTRACT:
A locking threshold has a hinged locking member receivable within a chamber within the threshold. The locking member is pulled from the threshold, and a locking flange is pivoted to a right angle from the threshold, and the floor. The locking member is then urged in, and moved sideways to lock the locking member with respect to the threshold. Screws extending through the threshold pass through the locking member, and slots in the locking member allow limited sliding movement of the locking member, and locking of the locking member.
