Strong magnets for heavy duty: the round base with 6 real N52 rare earth magnets has a super vertical magnetic attraction over 15 kg on a 5 mm thick sheet steel foundation. Size 43 x 6 mm, male thread size 1/4 inch - 20 x H 0.5 inch (height 12.7 mm). Anti-corrosion, anti-scratch and non-slip: All exposed metal components are made of 304 stainless steel. Coated rubber can protect the magnet from damage, avoid scratches on the paint surface and prevent the magnet from slipping on smooth surfaces.

Suitable for fixing perforated objects of different thicknesses. Ideal for PTZ, cameras, light strips, display boards, automatic devices, tools and machines. Waterproof for outdoor use: water-repellent and wear-resistant rubber coating. Loss of magnetic properties no more than 2% within 10 years. Long-lasting use even outdoors. We adhere to material standards: We insist on not using inferior magnets with low coercivity and reduced neodymium content. The use of Magnetpro magnets makes life more convenient. While maintaining absorbency, Magnetpro magnets also have excellent magnetic permeability.
