ABSTRACT:
A doorstop for use with swingable doors to prevent unauthorized entry into an area which includes a brace member pivotally connected to a base. The brace has an end for engaging the floor when the doorstop is in use. An angular orientation of the brace relative to the base is controlled by a lock bar having a T-shaped head connected by a shank to an enlarged inner end which is seated in non-rotational relationship to the base after being inserted in a first orientation through aligned slots in the base and brace member and then rotated to seat within the base.
