Abstract: An assembly and method for mounting a platform or deck to a number of support posts is disclosed. Each corner of the deck includes an open ended slot and an aperture above the slot. Each of the support posts includes a pair of holes arranged in corresponding fashion with the slot and aperture of the deck. Fasteners are partially inserted into one of at least two holes of the support posts such that the deck can simply be lowered onto the fasteners such that the fasteners are engaged by the slots of the deck and the deck may rest securely thereon. Finally, the installer can insert fasteners through the aperture and first hole and finish tightening the other fasteners to completely secure the deck to the support posts.
