Abstract: A cantilever assembly includes a cantilever arm having longitudinal fastening channels and slots in communication with the fastening channels. The assembly also includes an attachment bracket featuring a first leg portion and a second leg portion defining a seat there between with the leg portions featuring apertures. Bolts having threaded shafts are positioned through the apertures of the attachment bracket and engage the threaded bores of nut plates positioned in the fastening channels of the cantilever arm. As a result, when the bolts are turned, the nut plates engage side walls of the fastening channels and the distal ends of the bolts engage a central pipe portion of the cantilever arm.

Abstract: A cantilever assembly includes a cantilever arm having a pair of longitudinal fastening channels with a corresponding pair of slots in communication with the fastening channels. An attachment bracket features a connector portion and a pair of spaced leg portions defining a seat there between with each leg portion having at least one aperture. The leg portions also each have an inner surface featuring an elongated groove with each being in communication with a corresponding one of the apertures. The elongated grooves are positioned in alignment with the slots of the cantilever arm when the cantilever arm is positioned in the seat of the attachment bracket.
