This one-handed clamp features torsion-resistant I-profile rails made of cold-rolled steel, which are heat-treated and case-hardened. It has a smooth-running clamping handle that provides high clamping force. The Trulock pull mechanism allows for controlled release of the grip jaws. Switching from clamping to spreading can be done completely tool-free. The robust plastic body is fiberglass-reinforced, ensuring longer-lasting and more powerful clamping and spreading operations.
