Magnetic Base

General MG1758, Magnetic Base Holder.
No residual magnetism, when in the off position, to prevent scratching or other damage from inadvertent magnetism of chips or work pieces. On/Off switch energizes only when in use on work surface. V-groove for round surfaces; works on vertical or horizontal surfaces. Switching adapts easily to cam action for automatic setups, using magnetic base as an on/off holding device. Holds most dial indicators with center lug backs, universal indicator attachments, as well as other fixtures.
