Morris 91655 Heavy-Duty Lay-In Ground Pipe Clamp, 1-1/4" - 2" Pipe

Product Overview

The Morris 91655 is a UL467-listed heavy-duty side lay-in ground pipe clamp designed to bond grounding conductors to 1-1/4"–2" water pipe, conduit, or copper tubing.

Cast from high-strength, high-conductivity copper with stainless steel set screws, the 91655 accepts conductors from #8 AWG up to 4/0 for direct-burial grounding applications.

Key Features

• For 1-1/4"–2" pipe, conduit, or copper tubing
• Accepts ground conductor sizes #8 AWG through 4/0
• Side lay-in configuration for easier conductor placement
• Cast of high-strength, high-conductivity copper
• Stainless steel set screws
• UL467 listed for direct burial in soil or concrete

What this clamp does

The Morris 91655 provides a mechanically secure and electrically conductive connection between a grounding conductor and metallic pipe or tubing. Its side lay-in design allows the installer to place the conductor into the clamp from the side before securing.

• Creates a bonding connection for grounding and equipment grounding systems
• Supports heavy-duty conductors up to 4/0 for service and continuous ground loops

Where to use it

This clamp is intended for bonding to water pipe, conduit, or copper tubing with an outside diameter in the 1-1/4"–2" range. It is listed for direct burial, making it suitable for in-ground grounding applications where a buried clamp is required.

• Direct burial in soil or encasement in concrete (UL467 listing)
• Service grounding and continuous grounding loops where a lay-in configuration is preferred

Conductor and pipe compatibility

Confirm conductor size and pipe outside diameter before selecting this clamp. The 91655 accepts conductors from #8 AWG up to 4/0 and fits pipe or tubing with diameters from 1-1/4" to 2".

• Pipe range: 1-1/4"–2"
• Wire range: #8 AWG through 4/0

Basic installation method

Installers place the grounding conductor into the side lay-in opening, position the clamp on the pipe, and tighten the stainless steel set screws to secure the clamp and conductor. Use appropriate torque and installation practices per applicable electrical codes and project specifications.

• Side lay-in configuration allows conductor placement without threading through the clamp
• Set screws are stainless steel for corrosion resistance

Listings and environmental suitability

The 91655 is UL467 listed for direct burial, indicating it meets UL requirements for grounding and bonding clamps in buried or concrete-encased installations.

• UL467 listed for direct burial in soil or concrete

Before You Order

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

• Verify the pipe falls within the 1-1/4"–2" range and the conductor is within #8–4/0.
• Follow local electrical code and project-specific grounding requirements during selection and installation.
