Morris 91692 Serrated-Collar Cable-Adaptor Ground Clamp, 1-1/4" - 2" Pipe

Product Overview

The Morris 91692 is a copper serrated-collar cable-adaptor ground clamp designed to bond #8 through 4/0 armored cable or ground wire to 1-1/4"–2" water pipe, copper tubing, or a ground rod.

The clamp features a 360°-swinging serrated collar and adaptor for easy alignment and is cast from a high‑strength, high‑conductivity copper alloy with zinc‑plated steel set screws.

Key Features

• Bonds #8–4/0 AWG armored cable or ground wire to 1-1/4"–2" pipe, copper tubing, or ground rod
• Serrated collar and adaptor swing 360° for alignment
• Cast from high-strength, high-conductivity copper alloy
• Zinc-plated steel set screws for corrosion resistance

What this clamp does

The Morris 91692 provides a mechanical and electrical connection to bond armored cable or a grounding conductor to metal piping or a ground rod. It is intended for use where a secure, conductive connection is required between the conductor and 1-1/4"–2" pipe, copper tubing, or a ground rod.

• Creates a bonding path for grounding systems using armored cable or ground wire
• Serrated contact surfaces improve mechanical grip on the conductor and pipe

Compatible conductors and pipe sizes

Use this clamp with conductors and piping within the published size ranges.

• Wire range: #8 AWG up to 4/0 AWG (armored cable or ground wire)
• Pipe range: fits 1-1/4" through 2" water pipe, copper tubing, or ground rod

Materials and corrosion considerations

The clamp body is cast from a high-strength, high-conductivity copper alloy to provide a reliable electrical path. Set screws are zinc-plated steel to offer corrosion resistance where steel is used.

• Body: copper alloy (high conductivity)
• Set screws: zinc-plated steel

Basic installation and alignment

The serrated collar and adaptor swing through 360 degrees to help align the conductor and the clamp on the pipe before final tightening.

• Place the clamp around the pipe or tubing
• Rotate the serrated adaptor to align conductor and clamp
• Insert conductor or armored cable into the adaptor and tighten the set screws

Before You Order

Confirm the model number and the conductor and pipe sizes required for your application before ordering.

• Verify conductor size is within #8–4/0 AWG
• Verify pipe or tubing diameter is within 1-1/4"–2"
• Ensure the clamp style and materials are appropriate for your grounding or bonding installation
