This magnetic holder is designed to attach your measuring device to metal walls, such as the doors of a distribution board, during control cabinet construction, in vehicles, or even in shipbuilding. In addition to its magnetic function, the mounting kit also features a Euro hanger opening for attachment to wall hooks and holders on non-magnetic surfaces, allowing devices to be easily mounted on a perforated board or other mounting systems. With the tear-resistant strap, many measuring devices such as multimeters, laboratory thermometers, insulation testers, and various environmental measuring instruments can be secured to the magnetic holder. Additionally, work lights or smaller screw or tool bags can be conveniently attached at the work site. The attachment can be made either through a buckle or directly via an integrated Velcro fastener. The metallic surface is protected from scratches and damage by a full rubber coating of the magnetic holder, enabling its use on painted surfaces as well. With its wide range of applications and user-friendly handling, this mounting system is a must-have for every craftsman, installer, and technician.
