【180° adjustable magnetic holder】1/4"-20 male thread for the laser level, one 1/4"-20 and two 5/8"-11 female thread mounts on a tripod or laser mounting pole. The depth of the mounting screws on the edge of the bracket is 8 cm long and is suitable for laser levels that are less than 8 cm on the back. 【Magnetic design】: 2 permanent magnet alloy magnets ensure strong magnetic force and stable performance. With friction-enhancing rubber on the back and bottom, it is safe and non-slip. Please understand that the magnetic force and load-bearing capacity of the medium depends on the roughness and surface material of the adsorbed object. The load-bearing capacity tested on a 1 cm thick steel plate is 3.5 kg. 【Multiple installation methods】The magnet can be attached to a metal surface or steel plate. Three special nail holes are designed to make the installation much more solid. The groove design on both sides of the back of the bracket allows it to be attached to a rope. It can be mounted
