Greenfield 311-2 Strut Pipe Clamp 2 Inch Zinc Plated

Product Description

The GREENFIELD 311-2 is a zinc plated steel strut pipe clamp designed to secure 2-inch pipe to standard strut channel. Built from 14-gauge steel with a zinc plated and galvanized coating, this clamp delivers solid corrosion resistance in mechanical, plumbing, and electrical support applications. At 3 inches tall and 1.625 inches in length with a 0.25-inch wall thickness, it provides a rigid, low-profile mount suited for overhead or wall-mounted strut systems. Plumbers, pipefitters, electricians, and HVAC installers rely on this type of hardware to keep piping runs properly supported and aligned.

The 311-2 is used in commercial and residential mechanical rooms, utility spaces, and plenum areas where pipe must be clamped to unistrut or equivalent strut channel. It fits 2-inch pipe and installs on standard 1-5/8-inch strut. Typical applications include domestic water supply lines, conduit runs, refrigerant piping support, and drain line hangers where a durable, zinc coated clamp is required.

Compatibility

Designed as an OEM-style replacement and standard strut pipe clamp for use with 1-5/8-inch strut channel systems supporting 2-inch nominal pipe in mechanical and plumbing installations.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or HVAC technicians following local mechanical and plumbing codes. Shut off the piping system and relieve pressure before repositioning or securing existing lines. Use appropriate strut nuts and hardware rated for the load and environment. Do not overtighten fasteners, as this may distort the clamp or damage pipe coatings.
