Jorgensen steel bar clamps are seriously strong. Cast‑iron stationary and sliding heads with an orange, powder coated finish are merged with a high‑carbon, rust‑resistant steel bar that packs a whopping 80,000 pounds per square inch of tensile strength. The fast‑acting sliding head is acme threaded to accommodate a cold‑drawn steel screw with a large easy‑grip handle and swivel pad. And our original multiple‑disc‑clutch design allows the sliding head to hold securely at any point along the bar. Available in a wide variety of sizes and clamping forces for light‑duty, medium‑duty, and heavy‑duty applications.
