Irwin IR27ZR Locking Chain Clamp 9 Inches

Product Description

The IRWIN IR27ZR is a 20R locking chain clamp sized at 9 inches, designed to grip irregularly shaped workpieces that standard jaw clamps cannot secure. The chain mechanism wraps around round pipe, conduit, oddly shaped stock, and other non-flat surfaces, locking firmly in place to hold the workpiece during cutting, welding, or fabrication. This type of clamp is a standard hand tool used by pipefitters, plumbers, electricians, ironworkers, and general tradespeople across residential and commercial job sites. The locking mechanism provides repeatable, hands-free holding force once set, freeing the technician to work with both hands.

The IR27ZR suits applications where a conventional C-clamp or bar clamp would slip or fail to seat. Common use cases include holding pipe sections during threading or welding, securing conduit runs during layout, and clamping round or contoured material to a work surface or fixture. It is sold individually and is suited for both shop bench work and field use.

Key Features

• 20R locking chain clamp style grips round, irregular, and contoured workpieces
• 9-inch size provides reach suitable for mid-range pipe and conduit diameters
• Locking mechanism holds without continuous hand pressure
• Compact form factor supports both bench and field applications
• Sold as individual unit for single-tool procurement

Compatibility

Designed as an OEM-style locking chain clamp for general trade use on pipe, conduit, and irregularly shaped workpieces requiring a secure, hands-free grip.

Installation Notes

No power source or special tooling is required to operate this clamp. Inspect the chain and locking mechanism for wear or damage before each use. Do not exceed the rated clamping load for the tool. When used during welding or cutting operations, ensure the workpiece and clamp are properly grounded and that the chain is free of combustible debris.
