Irwin IR211ZR Locking C-clamp 18 Inch Extended Throat

Product Description

The IRWIN IR211ZR is an 18DR locking C-clamp built with an extended throat and regular tips, designed for heavy-duty gripping and clamping tasks in trade and industrial work. The extended throat depth provides clearance to reach further into a workpiece than a standard C-clamp, making it useful when the clamping point is set back from the edge of the material. At 18 inches in overall size, this clamp delivers significant reach and holding force. It is used by pipefitters, welders, ironworkers, and general contractors who need a reliable mechanical clamp for holding, bending, or positioning work.

The IR211ZR suits applications where a secure, adjustable grip is needed on metal, pipe, structural steel, or fabricated assemblies. The locking C-clamp format allows the user to set the jaw opening, apply the clamp, and lock it in place without continuous hand pressure. The extended throat configuration makes it particularly suited to welding setups and structural fabrication where standard throat depth would not reach the intended clamping point.

Key Features

• 18DR locking C-clamp design with extended throat for increased reach past workpiece edges
• Regular tips provide broad contact surface suitable for flat and structural stock
• 18 inches overall size for heavy clamping tasks
• Locking mechanism holds jaw position without continuous user pressure
• Sold individually (each)

Compatibility

Designed as an OEM-style locking C-clamp replacement or addition for trade and fabrication applications requiring an 18-inch extended-throat clamp with regular tips.

Installation Notes

Set the jaw opening to slightly wider than the workpiece before applying the clamp, then tighten the adjustment screw to achieve the desired clamping pressure at lockout. Inspect jaw tips before each use for wear or damage that could reduce grip or mar the workpiece. When clamping energized assemblies or near live circuits, de-energize and lock out the work area per applicable safety codes before applying the clamp.
