nVent CADDY Erico GR1181G Cadweld One-Shot Exothermic Weld Mold for 3/4-Inch Ground Rod

nVent CADDY Erico GR1181G Cadweld One-Shot Exothermic Weld Mold for 3/4-Inch Ground Rod

The nVent CADDY Erico GR1181G is a Cadweld® one-shot exothermic weld mold engineered for permanent, molecular-bond connections to 3/4-Inch ground rod. This single-use graphite mold is available for a 6-AWG conductor or a combined 8-AWG solid and 8-AWG stranded conductor option, giving electricians and grounding contractors a precise fit across the wire sizes most commonly paired with 3/4-Inch rod. As part of the nVent Cadweld exothermic welding system, the GR1181G mold supports rod-to-conductor terminations on commercial, industrial, and utility electrical projects where a low-resistance, code-driven grounding connection is required for the life of the installation.

Key Features

• Trade Size: Sized for 3/4-Inch ground rod, giving installers a precise mold fit without field measuring or guesswork.
• One-Shot Mold Design: Single-use graphite mold construction built for a dependable, repeatable exothermic weld on each individual connection.
• Conductor Size Range: Offered for 6-AWG conductor or a combined 8-AWG solid and 8-AWG stranded conductor configuration, covering the common grounding and bonding conductor sizes paired with 3/4-Inch rod.
• Cadweld® Exothermic System: Part of the nVent Cadweld exothermic welding product line used for permanent, code-driven electrical grounding and bonding connections.
• Molecular Bond Connection: Creates a true molecular bond rather than a mechanical connection, so the joint resists loosening and corrosion at the interface over the life of the installation.
• Purpose-Built for Rod-to-Conductor Terminations: Engineered specifically for ground rod to conductor exothermic welds, a common requirement on grounding and bonding system installations.

Technical Specifications

• Trade Size: 3/4"

Typical Applications

• Electrical Grounding and Bonding Connections
• Ground Rod to Conductor Exothermic Welding
