The Ideal Heavy Duty Fully Formed Screw Clamp offers a higher clamping force and at the same time reduces the risk of breaking the clamping arm, even if it is overloaded beyond the recommended tightening torque. The heavy duty steel profile is formed in one piece as the rail and upper arm in a high quality steel profile that gives the clamp a higher clamping force. The design allows the upper arm to yield slightly when maximum capacity is reached. This elasticity prevents breakage and damage to the clamp. The sliding arm is forged and reinforced to achieve a strong and stable construction. Movable pressure plate with rotation joint so it can be angled up to 35°. The sliding arm and steel rail are galvanized to avoid corrosion. The Powergrip handle is ergonomically designed and has a non-slip surface treatment to achieve an extra strong torque.
