Abstract: Apparatus and related methods relate to a wall-mounted rack with vertically offset shelving supports that create a backward-tilting shelf orientation. In an illustrative embodiment, the system may include T-arm brackets having vertical support members for wall attachment and horizontal extending members projecting outward. The horizontal extending members may, for example, receive a front cross-channel at a first mounting height. The horizontal extending members may, for example, also receive a rear cross-channel at a second mounting height lower than the first mounting height. The vertically offset cross-channels may, for example, support a shelf positioned at an anti-slide angle tilted toward the wall. The anti-slide angle may, for example, be created by the vertical height difference between the front and rear cross-channels. Various embodiments may advantageously provide high load capacity cantilevered wall shelving.
