Morris 90606 Copper Ground Clamp, 1-1/4" - 2" Pipe, 1" Conduit Hub

Product Overview

The Morris 90606 is a copper ground clamp with an integrated 1" rigid-conduit hub designed to bond a grounding conductor in rigid conduit to water pipe, ground rod, or copper-weld tubing.

The clamp accepts #2 to #10 AWG conductors, features a hub that swivels 360° for alignment, and is cast from a high-conductivity copper alloy with zinc-plated steel set screws.

Key Features

• 1" rigid-conduit hub with standard collar and adapter
• Hub swivels 360° for easy alignment during installation
• Accepts #2 through #10 AWG grounding conductors
• Designed for 1-1/4" to 2" water pipe, ground rod, or copper-weld tubing
• Cast from high-strength, high-conductivity copper alloy; zinc-plated steel set screws

What this clamp does

The Morris 90606 provides an electrical bond between a grounding conductor run inside 1" rigid conduit and metallic piping or grounding electrodes. It is intended to connect a grounding conductor in rigid conduit to water pipe, a ground rod, or copper-weld tubing.

Pipe and conductor compatibility

Confirm compatibility with the exact conductors and piping in your installation. The 90606 clamps to pipes with outside diameters in the 1-1/4" to 2" range and accepts grounding conductors sized from #2 AWG down to #10 AWG.

• Water pipe range: 1-1/4" – 2"
• Wire range: #2 to #10 AWG
• Conduit hub size: 1" rigid-conduit hub

Installation and alignment

The hub is designed to rotate a full 360° to allow easy alignment of the conduit before final tightening. Install by threading the rigid conduit into the hub, positioning the clamp on the pipe or rod, inserting the grounding conductor into the clamp, and tightening the set screws to secure the assembly.

• Hub swings 360° for alignment
• Thread conduit into hub, position clamp, insert conductor, tighten set screws

Materials and corrosion considerations

The body is cast from a high-strength, high-conductivity copper alloy to ensure effective grounding continuity. Set screws are zinc-plated steel to provide fastening strength.

• Clamp body material: copper alloy
• Set screws: zinc-plated steel

Before You Order

Confirm the model number and the pipe outside diameter and conductor size required for your application before ordering.

• Verify the pipe falls within 1-1/4" to 2" OD range.
• Verify the grounding conductor is within #2 to #10 AWG.
• Ensure a 1" rigid conduit hub matches your conduit threading and installation needs.
