Irwin Vise Grip 31 9SP 9″ Locking C-Clamp with Swivel Pads

The IRWIN VISE-GRIP 9SP is a 9″ locking C-clamp designed for reliable hold-down force on flat, round, and irregular work. With a 4-1/2″ jaw opening and 4-3/4″ jaw depth, it reaches around edges and into joints where standard clamps struggle. Swivel pads pivot to match tapered or uneven surfaces, spreading force to help prevent marring on sheet metal, tubing, hardwood face frames, and delicate assemblies. A turn screw lets users dial in clamping pressure for repeat work, while the classic trigger release unlocks smoothly with one hand. Manufactured from high-grade, heat-treated alloy steel, this clamp is built for everyday use in welding bays, fabrication shops, and woodworking benches. Whether you’re aligning miters, tacking brackets, or holding panels for drilling, the 9SP locking C-clamp delivers consistent grip and quick setup so jobs move faster with fewer adjustments.

Why Welders Prefer the Irwin Vise Grip 9″ Locking C-Clamp with Swivel Pads

Crews pick the IRWIN 9SP for dependable workholding on mixed materials and shapes. The swivel pads and deep throat make it useful on a welding table, when aligning sheet metal panels, or during cabinetry glue-ups where a standard clamp can’t reach. The locking C-clamp design holds steady while users position parts, drill, or tack weld, and the turn screw lets them repeat the same pressure across multiple pieces. For automotive bodywork, HVAC installs, and general fabrication, this vise grip clamp provides consistent clamping force, quick one-hand release, and material-friendly pads, helping reduce rework and keeping setups simple from the first fit-up through final fastening.
