Described herein are systems, modes, and methods for mounting one or more electronic housings to each other and to a rack mount system, a table mount system, or wall mount system. The mounting system includes a first pair of matching sliding panels that interface with each other in a slidingly engaging manner. Each of the first pair of sliding panels can be mounted to housings prior to being engaged with each other; the engagement of the first pair of sliding panels removably fixes the two housings together; additional housings can be fixed to the first two in a substantially similar manner. The first pair of sliding panels includes a U-shaped sliding panel and a C-shaped sliding panel, and according to a second embodiment, a second pair of sliding panels includes a C-shaped sliding panel and a Pi-shaped sliding panel. The second pair of sliding panels operates in a substantially similar manner as the first pair of sliding panels.

A mechanism for connecting two beams comprises a left beam and a right beam. The left beam is formed by an upper cross bar, a lower cross bar, and a vertical plate, the vertical plate has a width greater than a width of the upper cross bar and a width of the lower cross bar, the vertical plate has two edges protruding laterally away from the upper cross bar and the lower cross bar; the right beam has a vertical socket for receiving the vertical plate, the vertical socket is connected to the upper cross bar and to the lower cross bar, the vertical socket has two opposing curled lateral edges protruding laterally away from the upper cross bar and the lower cross bar, the two protruding edges of the vertical plate are inserted between the two opposite curled edges of the vertical socket.

There is provided a beam connector comprising first and second longitudinally-extending connector members. Each connector member includes a protrusion adjacent a first end portion thereof and which extends between a first side and a second side thereof. Each connector member includes a receptacle adjacent a second end portion thereof and which extends in an arc-shape laterally from the first side to the second side thereof. The receptacle of the first connector member is shaped to receive the protrusion of the second connector member. The receptacle of the second connector member is shaped to receive the protrusion of the first connector member.
