The Fatmax M one-handed clamp features a torsion-resistant I-profile rail made of cold-rolled steel, which is heat-treated and hardened. It includes removable protective caps with smooth and well-gripping surfaces. The clamp is equipped with an easy-to-use clamping lever that provides high clamping force. The Trulock pull mechanism allows for controlled release of the grip. Switching from clamping to spreading can be done without tools. The robust plastic body is fiberglass-reinforced, ensuring longer and more powerful clamping and spreading tasks.
