Abstract: An apparatus for securing a protective panel over a window includes at least one telescoping retainer bar that is tightly fixed within a window frame, adjacent the panel. Spring-biased locking buttons removably seat within one or more longitudinally-disposed apertures to fix the retainer bar at a desired length. At each end of the bar is a resilient pad that firmly engages one of two opposing sides of a window or door frame. One of the pads is movable relative to the bar to further tighten the bar within the frame once the telescoping bar has been extended as far as possible. The pad at the opposing end includes a biasing means for further anchoring the bar within the frame.

Abstract: A retaining bar for securing position of a protective panel within a recess of a building, such as a window frame or a door frame. The retaining bar has two telescopically engageable portions, which are tensioned in the frame. Each retaining bar member carries a resilient pad, which contacts the window or door frame once the bar members are extended to fit tightly within the flame. A threaded rod of one of the mounting assemblies allows tightening of the retaining bar in the frame.
