Morris 90601 Copper Ground Clamp, 1/2" - 1" Pipe, 1/2" Conduit Hub

Product Overview

The Morris 90601 is a copper ground clamp with a 1/2" rigid-conduit hub designed to bond a grounding conductor in 1/2" rigid conduit to 1/2"–1" water pipe, ground rod, or copper-weld tubing.

The hub pivots 360° for alignment. The clamp body is cast from a high-strength, high-conductivity copper alloy and uses zinc-plated steel set screws. It accepts conductors from #2 to #10 AWG.

Key Features

• 1/2" rigid-conduit hub with standard collar and adapter
• Hub swings 360° for easy alignment during installation
• Designed to bond grounding conductor in conduit to water pipe, ground rod, or copper-weld tubing
• Cast from high-strength, high-conductivity copper alloy
• Zinc-plated steel set screws for conductor and pipe clamping
• Accepts #2 through #10 AWG conductors

What this clamp is used for

The Morris 90601 is used to bond a grounding conductor routed inside 1/2" rigid conduit to an existing grounding electrode such as a 1/2"–1" water pipe, a ground rod, or copper-weld tubing. The integral conduit hub provides a threaded entry for the rigid conduit while maintaining a secure electrical connection to the clamp body.

Pipe, conduit and conductor compatibility

Confirm sizes before ordering: the clamp fits water pipe from 1/2" to 1", provides a 1/2" rigid-conduit hub, and accepts conductors in the range #2 to #10 AWG.

• Water pipe range: 1/2" – 1"
• Conduit hub size: 1/2" rigid-conduit
• Wire range: #2 to #10 AWG

Installation and alignment

The hub swings 360° to allow easy alignment of the rigid conduit during installation. Typical installation steps are to thread the conduit into the hub, position and clamp the assembly to the pipe, insert the grounding conductor, and tighten the set screws to secure electrical and mechanical contact.

• Hub rotation: 360° swivel for alignment
• Set screws secure both the conductor and clamp to the pipe

Materials and durability

The clamp body is cast from a high-strength, high-conductivity copper alloy to provide a reliable conductive path for grounding. Set screws are zinc-plated steel.

• Clamp material: copper alloy (cast)
• Set screw material/finish: zinc-plated steel

Before You Order

Confirm the model number and required sizes before ordering. This page describes a single SKU (Morris 90601) with a 1/2" rigid-conduit hub and compatibility with 1/2"–1" pipe and #2–#10 conductors.

• Verify your pipe outer diameter falls within 1/2"–1" before installation.
• Verify the grounding conductor is within the #2–#10 AWG range.
• Ensure the 1/2" rigid conduit threading and adapter requirements match the job site conduit.
