Morris 91712 Lay-In Rebar Ground Clamp, 3/8" Rebar

Product Overview

The Morris 91712 is a lay-in copper alloy ground clamp designed to bond a #6–#8 AWG grounding electrode conductor to 3/8" bare rebar.

Cast from a high-strength, high-conductivity copper alloy with stainless steel hardware and UL467 listing for direct burial in soil or concrete; not for use on epoxy-coated rebar.

Key Features

• Lay-in design for quick connection to continuous ground loops
• Fits 3/8" bare rebar
• Accepts #6 AWG through #8 AWG grounding conductors
• Cast from high-strength, high-conductivity copper alloy
• Stainless steel hardware for corrosion resistance
• UL467 listed for direct burial in soil or concrete
• Not suitable for epoxy-coated rebar

Function

The Morris 91712 provides a secure electrical bond between a grounding electrode conductor and a 3/8" bare reinforcing bar (rebar). The lay-in design allows the conductor to be placed into the clamp without threading it through, which is useful for continuous ground loops and retrofits where the conductor cannot be run through the rebar.

• Connects grounding electrode conductor (wire) to rebar
• Wire range: #6 AWG – #8 AWG

Typical Applications

Use this clamp where a grounding conductor must be bonded to bare rebar in concrete-encased electrodes and other grounding installations. Common environments include concrete foundations, pools and spa bonding, telecom grounding, agricultural installations, and marine work where direct burial is appropriate.

• Concrete-encased electrode grounding
• Pools/spas and related bonding
• Telecom grounding and equipment grounding
• Agriculture and marine grounding where bare rebar is present

Installation and Use

The lay-in feature lets you position the clamp on 3/8" bare rebar, place the grounding conductor into the clamp, then tighten the stainless steel hardware to secure the connection. The product is not intended for use on epoxy-coated rebar—do not install on coated surfaces.

• Place clamp on bare 3/8" rebar
• Lay conductor (#6–#8 AWG) into the clamp
• Tighten stainless steel hardware to secure the conductor

Materials and Listing

The clamp body is cast from a high-strength, high-conductivity copper alloy to provide reliable electrical continuity. Hardware is stainless steel for corrosion resistance. The unit is UL467 listed for direct burial in soil or concrete, confirming suitability for encased or direct-burial grounding installations.

• Body: copper alloy (high-strength, high-conductivity)
• Hardware: stainless steel
• Listing: UL467 for direct burial in soil or concrete
