Delivering up to 1,540 lbs. of nominal clamping force with a 4-1\/2 in. throat depth, this industrial F-style clamp provides high holding power and structural rigidity for high-pressure gluing and assembly work.\u003c\/p\u003e\n\u003cp\u003eConstructed with corrugated malleable cast iron fixed and sliding jaws, the TGK series resists twisting and deformation under heavy clamping loads. The cold-drawn, profiled steel rail features serrations on six faces, working in tandem with BESSEY's integrated anti-slip system—a set screw molded into the sliding arm—to prevent accidental slipping during tightening. A smooth-running, hardened ACME-thread spindle maximizes clamping pressure with reduced cranking effort, while the ergonomic 2K two-component composite handle provides comfortable leverage and grip.\u003c\/p\u003e\n\u003ch3\u003eFeatures \u0026amp; Benefits\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e1,540 lbs.
