ABSTRACT:
A modular protective grill is disclosed for removably overfitting a building opening, such as a window. The grill includes a decorative central body which terminates vertically in an upper tubular frame member and a lower tubular frame member. Tubular side attachment bars are affixed to the window jambs and upwardly and downwardly carry telescoping vertical frame extensions. Horizontal frame extensions telescope within the lateral ends of the upper and lower tubular frame members and respectively carry vertical pivot pins. The pivot pins insert into the free ends of the vertical frame extensions to allow the central body to pivot about either side attachment bar by disconnecting the opposite side. The protective grill includes tamper-proof break-away construction members to permit emergency egress upon opening a side of the grill construction.
