This floating shelf bracket is designed to support shelves ranging from 250-300mm in length, 200mm in depth, and a minimum of 25mm thickness. The bracket is screwed to the wall, and the shelf is then slipped onto the pipe arms. The shelf can be secured to the bracket using the two holes in the pipe arms. The pipe arms have a slight upward angle to compensate for any shelf sag under load. The bracket base piece measures 185mm long x 24mm deep and is 2mm thick. The bracket pipe arms are 13mm in diameter and 130mm long from the front face of the base. Six holes are provided for wall fixing, but more can be drilled if needed to align with studs in cavity walls. The weight capacity of this bracket is entirely dependent on the wall fixings and the size of the shelf used. Multiple brackets can be used for longer shelves. Hollow wall anchors, minimum 3 per bracket, are recommended for cavity walls. Dimensions: Length: 185mm, Height: 22mm, Tube Length: 135mm, Tube Diameter: 13mm, Centre To Centre Tubes: 100mm. It is recommended to purchase drill bits and other tools after receiving your order to ensure compatibility. Video demonstrations are available.
