These holders provide support for glass or wooden shelves, and have the advantage of a tilt adjustment mechanism to raise the leading edge of the shelf for levelling.
Adjustable to accommodate shelf thicknesses from 7mm to 41mm (9/32" to 1 9/16"), each has an upper jaw mechanism that mounts to a wall and an interlocking lower jaw support. Turning an adjuster screw in the underside of the support arm (using a #2 Phillips or POZIDRIV bit) raises or lowers the front of the shelf within a 3mm (7/64") range, letting you set the shelf level or tilted slightly upwards to ensure items won't roll off.
While each support has a load rating of 25kg (55 lb), its actual capacity depends not only on the material to which it is mounted and the fasteners used, but also on the depth of the shelf. If installed with the included screws and anchors in 5/8" drywall, a pair of holders can be expected to support a 300mm (12") deep shelf weighing up to 18kg (40 lb). Made of strong zinc alloy with a silver or stainless-steel finish, and non-marring plastic shelf contact surfaces.
