4-1/2 in. "O" Series Bridge C-Clamp, Full Closing Spindle, 2-7/8 in. Throat Depth

The Wilton 4-FC “O” Series Bridge C-Clamp is built for the most demanding heavy industrial applications, including shipbuilding, structural fabrication, and heavy construction. The drop forged frame features a black oxide coating for lasting corrosion resistance and durability on the job. The full-closing square-head spindle is machined from a single piece of cold drawn steel, tempered and hardened, delivering clamping force up to 40,000 lbs. Its large-diameter rolled thread and hardened point ensure smooth operation under extreme loads, while the hot upset square head withstands heavy wrench tightening without deforming. This clamp provides the reliability and brute clamping strength contractors need when standard clamps simply won’t cut it.
