Heavy-duty floating shelf bracket engineered for professional installations. This single bracket supports up to 20kg per pair when properly secured into solid masonry and timber stud wall with 300mm deep shelves spaced maximum 60cm apart. The compact 45x30mm steel base features four slotted holes for precise alignment and fits standard timber studs in cavity walls. The 200mm support rod (16mm diameter, adjustable for shallower applications) accommodates shelves 30-35mm thick up to 300mm depth. Ideal for custom shelving projects requiring invisible support and maximum load capacity. Spacing multiple brackets closer together or using cavity wall anchors enhances weight distribution and structural integrity. A great trick when fixing into the timber stud work is to cut the sheet out where the timber stud and recess the bracket base straight onto it, this saves you from then having to rebate the back of the shelf.
