Description:Magnetic base holder also known as universal base holder is widelyused in the machine manufacturing industry, which is also used in variousscientific research institutions. There is a cylinder with a bar-shapedpermanent magnet inside it. And the position of the outer base is a softmagnetic material, which is a kind of ferrite material that is easy tomagnetize or demagnetize in the weak magnetic field.Features:1. Switch on/off magnetic base to move at any time without reactionforce, avoiding damage to the gauge and working desk.2. The base is equipped with a permanent alloy magnet and a centrallocking mechanism with anti-loose springs.3. Made of highly wearproof alloy steel, the shell is chrome-platedto achieve rust-proof, durable and beautiful results.4. Concise structure, easy to use and maintain, high sensitivity,stable and reliable.5. Smooth universal painted chrome arm can be fixed at any angle,easy and quick to use, widely used in mechanical correction and technicalmeasurement.Specifications:Material: Alloy steelColor: RedHolding Force: Approx. 7kgOverall Height: Approx. 35cm/13.78inClamping Hole Diameter: Approx. 8mm/0.31inBase Holder Size(L*W*H): Approx. 60x50x55mm/2.36x1.97x2.17inWeight: Approx. 1197gPackage Includes:1 x Universal Magnetic Base HolderNote:1.
