A fire escape device has a box with a back panel secured to side panels and to two bottom end panels. A bottom central panel lies between the bottom end panels and is hinged to the back panel. A front panel is hinged to the bottom central panel and has a bottom edge rabbet interfitting with the front edge of the bottom end panels. A removable top panel has angles engaging the upper edges of the back panel and of the front panel and is short to leave end openings above the bottom end panels through which ornaments on the bottom end panels may project. The box is secured to a building by brackets secured to the back panel and the two bottom end panels. Brackets of one design lie over a balcony rail, and brackets of another design are bolted to the building wall. A ladder including side chains and cross rungs is disposed on the bottom central panel with the chains extending through cutouts in the top panel. Weight on the ladder is transmitted through quick screw links passing through holes in the brackets or alternatively to an extensible rod adapted to rest on the top panel and to be moved through a building window and then extended to engage the inside frame of the window.
