Burndy GRL5 Ground Rod Clamp, Light Duty, Copper Alloy

The Burndy GRL5 is a light duty mechanical ground rod clamp built to join copper conductors ranging from #10 AWG to #2 AWG to a 5/8" ground rod. Constructed from copper alloy with an unplated finish, this compact acorn-style connector measures approximately 0.94" x 1.34" and delivers a secure, code-driven cable-to-rod mechanical connection for grounding electrode systems. As part of Burndy's copper mechanical grounding connector line, the GRL5 is engineered for electricians who need a dependable, easy-to-install clamp for service and utility grounding work where a bolted mechanical termination is preferred over crimping.

Key Features

  • Ground Rod Size: Sized for 5/8" ground rods, giving installers a precise fit for a secure cable-to-rod grounding connection.
  • Durable Construction: Copper Alloy body construction resists corrosion for long-term reliability in below-grade, outdoor, and high-moisture grounding environments.
  • Mechanical Clamp Design: Light Duty acorn-style mechanical connector allows quick field installation without crimping tools or special dies.
  • Conductor Range: Accepts copper conductors from #10 AWG through #2 AWG, giving flexibility across common grounding electrode conductor sizes.
  • Compact Footprint: Approximate 0.94" x 1.34" body fits neatly into ground rod wells, meter enclosures, and other tight grounding locations.
  • Finish: Unplated copper alloy construction keeps the connector consistent with bare copper grounding conductors.
  • Cable-to-Rod Configuration: Purpose-built to terminate a stranded copper cable directly onto a driven ground rod as part of a grounding electrode system.

Burndy GRL5 – Frequently Asked Questions

1) Which ground rod diameters does the Burndy GRL clamp fit?
Two sizes are offered: the GRL5 for 5/8 inch ground rods and the GRL6 for 3/4 inch rods. Pick by the rod actually driven in the ground, not by the conductor size. A 5/8 inch clamp will not close properly on a 3/4 inch rod, so if you are grounding utility or service work where 3/4 inch rods were specified, order the GRL6.
2) What size grounding conductor can I land in a Burndy GRL ground rod clamp?
The GRL clamp takes stranded copper from #10 AWG through #2 AWG. That covers the usual grounding electrode conductor sizes on residential and light commercial services. If your GEC is larger than #2, such as #1/0 on a big service, this light duty clamp is not the right part and you need a heavier mechanical ground rod clamp rated for the larger range.
3) Do I need a crimping tool or dies to install this ground rod clamp?
No. The GRL is an acorn-style mechanical clamp, so it's a bolted termination you tighten in the field with hand tools. No crimper, no dies, no hydraulic head. That's why electricians reach for it on service and utility grounding where a compression connector would mean hauling tooling to the hole.
4) Is a copper alloy ground rod clamp OK to bury in direct contact with soil?
Yes, the GRL is built for below-grade use. The body is copper alloy and left unplated, which keeps it consistent with bare copper grounding conductors and avoids dissimilar-metal issues at the rod. Typical placements are ground rod wells, below-grade connections at the rod head, and meter enclosure grounding.
5) What is the difference between a light duty and heavy duty ground rod clamp, and which do I need?
The GRL is the light duty version: single bolted acorn clamp, copper conductors #10 through #2, cable-to-rod only. It suits standard service entrance and panelboard grounding. Step up to a heavy duty ground rod clamp when the conductor is larger than #2, when the clamp has to take more than one conductor, or when the job spec calls for a direct-burial heavy-duty connector.
6) Can I use the Burndy GRL clamp to splice two grounding conductors together?
No. It's a cable-to-rod connector, built to terminate one stranded copper conductor onto a driven ground rod. For conductor-to-conductor splices or cable-to-cable taps you need a split bolt or a grounding tap connector instead.
7) What are the Burndy part numbers for the 5/8 inch and 3/4 inch ground rod clamps?
Order GRL5 for the 5/8 inch rod and GRL6 for the 3/4 inch rod. Same light duty copper alloy acorn design, same #10 to #2 AWG copper conductor range; the only difference is the rod diameter the saddle closes on.
8) Will a light-duty acorn clamp fit inside a ground rod well or an inspection box?
It should. The GRL5 body measures roughly 0.94 x 1.34 inches, which is small enough for ground rod wells, meter enclosures, and other tight spots where a bulkier heavy-duty clamp fights you for room.
