Blackburn GR58-300500 – Frequently Asked Questions
1) Will the GR58-300500 work with aluminum conductor?
No. The conductor material on this fitting is copper, so it is intended for copper grounding conductor on a 5/8 inch rod. Terminating aluminum here is a dissimilar-metal connection the fitting is not rated for.
2) Is a compression ground rod connector better than a mechanical clamp for a buried electrode?
Compression is the choice where the connection gets buried or encased and will never be accessible again. The GR58-300500 is an E-Z-Ground compression fitting, crimped once with a die tool to form a permanent copper-to-rod joint, so there is no bolt to back off with thermal cycling or soil movement. A bolted acorn or pipe clamp is the better pick only when you need the connection to be removable for testing or future re-termination.
3) Do I need a crimp tool for the Blackburn Figure 8 grounding connector, and does it come with one?
The GR58-300500 ships as a single connector, sold each, with no tooling included. A compression fitting this size needs a hydraulic or battery crimper with the correct die for the Figure 8 body, so order the tool and die separately if your crew does not already carry them.
4) Is the Blackburn GR58-300500 made in the USA for Buy American grounding specs?
Country of origin on this connector is the United States, which is the answer a government, education, or healthcare procurement office needs when a domestic-content clause is on the purchase order.
5) How many GR58-300500 connectors do I get per order?
One. The selling unit is each, so for a service with multiple rods or a ground ring with several taps, multiply your count by the number of terminations, not the number of rods.
