Spark-Duty Drop Forged Hi-Vis C-Clamp 0 - 4-1/4 in. Opening Capacity, 3-1/4 in. Throat Depth

Opening from 0 to 4-1/4 in., this clamp delivers 6,200 lbs. of clamping force with a 3-1/4 in. throat depth. Purpose-built for steel fabrication and welding environments, the copper-plated spindle resists weld spatter fusion that seizes standard spindles after repeated exposure. The high-visibility safety orange finish makes this clamp immediately identifiable in busy fabrication shops, overhead crane setups, and multi-station welding cells. Drop forged steel construction delivers frame strength that handles the thermal stresses of welding-adjacent clamping without distortion. The hardened acme thread spindle maintains smooth operation even after extended heat exposure, and the swivel pad conforms to workpiece contours. When welding fixtures demand clamps that stay visible, stay functional, and resist spatter damage, the Spark-Duty Hi-Vis is the professional-grade answer.
