Irwin 27ZR Locking Chain Clamp 9 Inch 18 Inch Chain

Product Description

The IRWIN INDUSTRIAL TOOL CO 27ZR is a 9-inch locking chain clamp designed to grip and secure irregular, round, and odd-shaped workpieces that standard jaw clamps cannot handle. Built from high-grade alloy steel, the 27ZR uses an 18-inch effective chain length to wrap around virtually any profile. The ratcheting adjustment mechanism allows the chain to tighten or release quickly in either direction, and the locking mechanism is engineered to prevent slippage once set. This tool is used by plumbers, pipefitters, HVAC technicians, electricians, and fabricators who regularly work with pipe, conduit, tubing, and other non-flat stock.

The 27ZR suits trade applications where a fixed-jaw locking plier cannot achieve a secure hold. Common uses include gripping round or irregularly shaped pipe during cutting, threading, or assembly; holding conduit runs during layout; and clamping formed sheet metal or structural shapes during fabrication. The 9-inch overall tool length and 18-inch chain make it practical across a wide range of stock diameters encountered in residential and light commercial trade work.

Key Features

• 18-inch effective chain length wraps and locks around any shape or size workpiece
• Ratchet-action adjustment moves in either direction for fast setup and release
• High-grade alloy steel construction for durability under trade jobsite conditions
• Powerful locking mechanism engineered to prevent slippage once engaged
• 9-inch overall tool length suited to a wide range of pipe and stock diameters

Compatibility

Designed as an OEM-style replacement or addition to standard locking plier sets used in plumbing, HVAC, electrical, and general fabrication trade applications.

Installation Notes

Locking chain clamps are typically used by licensed plumbers, pipefitters, HVAC technicians, and electricians as a gripping and holding tool rather than a fixed installation component. Before use, ensure the workpiece is stable and the chain is fully seated against the surface before engaging the lock. Inspect the chain and locking mechanism for wear or deformation prior to each use. Follow applicable jobsite safety guidelines when working with pressurized pipe or energized conduit systems.
