A tank rack may have a back frame member and at least two tank support members spaced apart from one another along the back frame member. Each of the tank support members may have two inner sections, two outer sections and a rear portion. The rear portion may be connected to the back frame member.

A shelving system with a shelf, two rear vertical posts and two front vertical posts. The posts all have vertically spaced apart shelf supports thereon and the shelf has side support rails that are received between two of the vertically spaced apart shelf supports on the front vertical posts and two of the vertically spaced apart shelf supports on the rear vertical posts. The rear of the shelf can be raised or lowered and re-attached in a new position while the side support rails remain positioned between the shelf supports in the front vertical posts. If the rear or front of the shelf is accidentally dropped, the shelf rotates such that the side rails lock against the top and bottom of the vertically spaced apart shelf supports, thereby preventing the shelf from falling.

A shelving system is provided. The shelving system includes an upper rail, and optionally a lower rail, from which one or more upright supports extend. The upright supports are slidable within the upper and lower rails so that a user may vary their location. A shelf mounts to the upright supports. The shelf includes interlocking deck panels and selectively removable support bars so that it may be assembled onto the upright supports.

A shelving system with a shelf, two rear vertical posts and two front vertical posts. The posts all have vertically spaced apart openings passing therethrough. The shelf has a pair of front side support arms that pass through the apertures in the front vertical posts and a pair of rear side support arms that pass through the apertures in the rear vertical posts. The rear of the shelf can be raised or lowered and re-attached in a new position while the front side support arms remain positioned within the apertures in the front vertical posts. If the rear of the shelf is accidentally dropped, the shelf rotates such that the front side support arms lock against the top and bottom of the vertically spaced apart apertures, thereby preventing the shelf from falling.
