Throat Depth, 2K Handle TG4.512+2K","description":"\u003cp\u003eThe BESSEY TG4.512+2K is a heavy-duty malleable cast iron F-style bar clamp engineered for woodworking, cabinetry, fabrication, and general workshop assembly. Featuring a 12 in. clamping capacity and a 4-1\/2 in. throat depth, this clamp delivers up to 1,000 lbs. of rigid nominal clamping force to hold workpieces securely during glue-ups, machining, and structural joinery.\u003c\/p\u003e\n\u003cp\u003eConstructed with corrugated malleable cast iron jaws and a high-quality profiled steel rail, the clamp provides high resistance to torsional twisting and flexing under load. The upper jaw is swaged directly to the rail without mechanical fasteners, eliminating joint loosening over time. To ensure operator safety and setup security, the sliding arm incorporates an anti-slip set screw that interlocks directly with six-face rail serrations to prevent slippage when positioning.\u003c\/p\u003e\n\u003cp\u003eClamping pressure is applied using a hardened spindle equipped with smooth-running ACME threads, maximizing force output while minimizing cranking effort. The ergonomic 2K composite handle provides a comfortable, high-friction grip that allows operators to apply full clamping torque with reduced hand fatigue. Field-replaceable pressure pads protect delicate workpiece surfaces and simplify long-term maintenance.\u003c\/p\u003e\n\u003ch3\u003eFeatures \u0026amp; Benefits\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorrugated Cast Iron Jaws:\u003c\/strong\u003e Reinforced malleable cast iron upper and lower jaws generate rigid clamping pressure without bending or twisting.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2K Composite Handle:\u003c\/strong\u003e Ergonomic two-component grip maximizes hand torque and slip resistance to reduce fatigue during repeated clamping.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIntegrated Anti-Slip System:\u003c\/strong\u003e Set screw molded into the sliding arm interlocks with rail serrations to keep the arm locked firmly in place.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProfiled Steel Rail:\u003c\/strong\u003e Precision-drawn profiled steel rail reinforces the structure against high torsional forces.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSix-Face Rail Serration:\u003c\/strong\u003e Multi-sided serrations provide continuous positive locking for the sliding jaw.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eACME Thread Spindle:\u003c\/strong\u003e Hardened, smooth-running spindle with ACME thread delivers rapid travel and high force conversion.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSwaged Upper Jaw:\u003c\/strong\u003e Fixed jaw is press-fitted to the rail to maintain structural alignment without threaded fasteners.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eField-Replaceable Pad:\u003c\/strong\u003e Pressure pad can be replaced without specialized tools to protect workpieces and extend tool life.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e(1) BESSEY TG4.512+2K 12 in.
