Cast-iron stationary and sliding heads with an orange, powder coated finish are merged with a high-carbon, rust-resistant steel bar that packs 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.
Original multiple-disc-clutch design allows the sliding head to hold securely at any point along the bar.
