Abstract: Writing desks and other office equipment are commonly cantileverly supported upon arm-like multi-hooks brackets, the bracket being hookably attached within vertically spaced and vertically elongated apertures of an upright column. Inasmuch as a bracket hooked portion can only partially occupy the height of a column aperture, accidental upward bumping of the bracket can dislodge it from the upright column thus endangering the cantileverly supported office equipment. The multi-hooks bracket described herein is provided with a notchably serrated type lock that cooperates with a bracket hook to effectively together occupy the entire height of a column aperture, so that the bracket is made resistive to accidentally imparted upward forces. The multi-hooks bracket disclosed herein is preferably singularly constructed, and along distinctly different upright planes, of a laminar structural material, such construction providing an unusually strong and economical cantilever support for office equipment.
