With the demand on the power grid increasing daily, it’s vital to have reliable products throughout power infrastructure. In addition, updating current infrastructure is essential to handling disruptions and avoiding outages.

Using nVent ERICO’s innovative nVent ERICO Hammerlock Ground Clamp irreversible mechanical connection makes connecting the grounding conductor to the ground rod as simple as swinging a hammer. nVent ERICO Hammerlock can be installed three to five times faster than an acorn clamp. nVent ERICO Hammerlock is also suitable for Copperweld® steel conductors.

  1. Fast and simple installation requires only a hammer

On most projects, labor is significantly more expensive than parts. Thus, it is essential to quickly and successfully install the product, saving time and money. nVent ERICO Hammerlock Ground Clamps only require a hammer for proper installation, saving the installer time and eliminating the need for tool changes.

  1. Provides a visual indication of completed connection

nVent ERICO Hammerlock visually indicates a complete connection, ensuring the system is installed correctly and reducing the need for rework. This visual connection makes you feel safe and confident that the installation is done correctly.

  1. No special training required

The simplified installation process of the nVent ERICO Hammerlock Ground Clamp allows for installation without any special training. This product feature simplifies the installation process by allowing available people on the job site to take on the task with minimal interruptions.
