Made in Europe, unique discreet polycarbonate grey finish shelf clip brackets (pair of). Simply fix to the wall with a single screw and plug fixing for masonry wall installation. (screws and wall plugs supplied). A 19mm thickness shelf slots tightly into the bracket slot covering the screw fixing, and giving the shelf a floating effect such as the lite 19mm thick shelves here . Maximum spacing for best weight capacity at wall stud distance, or approximately 400mm apart fitted to solid walls supporting a maximum shelf depth 300mm. Please note the screws and plugs supplied are for solid brick type wall fixing, or the screws (without the plugs) can be used to fit the brackets to the wooden stud in a hollow cavity wall for the maximum weight capacity. Quality hollow wall anchors here can be used to fit the brackets to gyprock sheet, one fixing per bracket is required. Weight capacity will then be limited to the strength of the gyprock sheet but expect up to 10kg per pair when fitted using the recommended wall fixings. For higher weight capacity we recommend to use 3 brackets to mount shelves of 800mm or longer, or 300mm deep spacing the brackets equally along the length of the shelf.
