Quick-Release Magnetic Brackets


150 lbf Maximum Pull	235 lbf Maximum Pull	245 lbf Maximum Pull

400 lbf Maximum Pull	600 lbf Maximum Pull

An on/off magnet control makes it easy to move and attach these brackets to metal surfaces. Secure items to the bracket plate. Magnets are made of neodymium (neodymium-iron-boron), a rare earth material. They have a case that concentrates and focuses the magnetic field. It also protects the magnetic material.

Warning: Maximum pull ratings are based on direct contact with rust-free and unpainted iron plate. Variations in material condition will significantly reduce these ratings. Do not use for lifting over people.

Easy On/Off Neodymium Magnets

Turn magnetic force on or off with a simple twist. These magnets grip firmly and release quickly, making them best for fixtures, positioning tasks, and quick-change setups. With the highest strength-to-size ratio of any magnet, these deliver a powerful and even pull force across surfaces.

Warning: Maximum pull ratings are based on direct contact with rust-free, unpainted iron surfaces. Variations in material condition will significantly reduce these ratings. Do not use for lifting over people.

Standard Magnets

Nickel-Plated Steel Case—Offers similar corrosion resistance to chrome plating to withstand salt water and chemicals. However, nickel is more likely to wear off over time.

Easy On/Off Magnetic Clamps


Style A	Style B	Style C	Style D	Style E

Switch the magnets on these clamps on and off for easy placement and removal of your workpiece.

Style E—Style E have magnets on opposite sides that can be turned on and off independently, letting you adjust one workpiece while the other remains clamped in place. They’re commonly used to weld two pieces of metal together.
