A powerful permanent magnetic type base holds to any steel or iron surface - horizontally, vertically or up side down, thus eliminating time spent on clamping indicator to machine. 
When magnet is turned 'ON' by the knob, the base remains firmly clamped in any desired position. The base and two sided energized for attachment on flat surfaces and a 'V slot facilitates gripping of the stand of shafts with a diameter range of 20 to 120 mm. 
The unique clamping which can hold dial indicator 8 mm or 5/16" stem diameter simple and quick setting is obtained by a new clamping of the extension arm, which guarantees absolutely rigid clamping even with moderate tightening. Magnet should be turned "OFF" when not in use.
