Brute Force Bridge C-Clamp "O" Series, 0 - 4-1/2 in. Open Capacity (4-FC)

Delivering 20,000 lbs. of clamping force, this clamp opens from 0 to 4-1/2 in. with a 2-7/8 in. throat depth. The full closing spindle design allows the jaw to close completely to zero, accommodating the thinnest materials without losing clamping effectiveness. Built as a bridge-style frame, this clamp distributes loads across a wider footprint than standard C-clamps, reducing localized stress on workpieces and improving fixture stability. Forged steel construction handles the demanding loads of heavy fabrication, press work, and production welding without frame distortion. The acme thread spindle is hardened for extended service life in high-cycle industrial environments where clamps are tightened and released hundreds of times per shift. A swivel pad at the spindle tip conforms to workpiece surfaces for even pressure distribution on both flat and contoured stock.
