Arlington Industries 721B Solid Brass Bare Wire Ground Clamp, 1-1/4" to 2" Pipe

Arlington Industries 721B Solid Brass Bare Wire Ground Clamp

The Arlington Industries 721B is a solid brass bare wire ground clamp built to secure grounding conductors to metal pipe ranging from 1-1/4" to 2" in diameter. Constructed with a solid brass body and fitted with steel screws, this ground clamp provides a dependable mechanical connection point for bonding a bare copper grounding conductor to water pipe, conduit, or other metallic piping used as a grounding electrode. The 721B gives electricians a straightforward way to establish a secure, code-compliant grounding electrode connection on jobs where a bare wire clamp-style fitting is required rather than a screw-terminal or lay-in style clamp. This ground clamp is well suited for electricians and maintenance professionals who need a simple, effective way to bond a bare grounding conductor to metallic pipe during new construction or service upgrades.

Key Features

• Trade Size: Sized to fit pipe diameters from 1-1/4" to 2", covering common water service and conduit pipe sizes found in residential and commercial buildings.
• Durable Construction: Solid brass body resists corrosion, helping the clamp maintain a stable, low-resistance ground path over years of service in damp basements, crawlspaces, and mechanical rooms.
• Steel Screws: Equipped with steel screws that draw down tight to clamp the ground wire firmly and hold the connection secure against vibration and movement.
• Bare Wire Design: Designed to accept a bare copper grounding conductor for a direct, uninsulated connection to the pipe surface.
• Solid Brass Body: Non-ferrous brass construction stands up to moisture exposure better than plain steel, making it a practical choice for grounding electrode connections in wet or below-grade locations.
• Compact Clamp Profile: The clamp's low-profile design fits tight to the pipe, making it easier to route and dress the bare grounding conductor in crowded mechanical spaces.
