The Locking MG Series is a range of light to medium duty clamps with holding pressures ranging between 100 & 370 daN. Ideally suited for light to medium duty assembly. Locking Lever secures clamp in closed and open positions. The locked closed position, provides additional safety in applications where the clamp remaining locked is critical. The locked open position can used to prevent clamp arms from falling closed when the clamp is not mounted in the vertical position.
