7" Extractor Locking Grounding Pliers

Product Overview

GPB700 Series – PBX-Style Copper Contact Grounding Pliers

The GPB700 Series builds on a proven PBX-style plier platform and upgrades it for improved conductivity, stronger grounding performance, and more control in demanding welding environments. Designed for professional fabrication, repair, and industrial welding applications, each model features heavy-duty construction paired with precision copper contact surfaces to ensure stable, low-resistance grounding under high current loads.

Engineered for durability and ease of use, the series offers multiple configurations to match different shop and field requirements; from fixed-jaw simplicity to adjustable opening control and enhanced copper wire connection systems.

Applications

  • Welding fabrication and assembly
  • Industrial maintenance and repair
  • Structural steel and metal construction
  • Heavy-duty grounding and electrical contact setups

The GPB700 Series delivers a scalable grounding solution, combining PBX-style mechanical strength with upgraded copper conductivity options to meet the demands of modern welding operations.

When The Copper Grounding Is Removed

Dual-Position Locking: The two-position locking mechanism makes it easy to grip 2" pipes.(Avaialable in the GBP720 & GBP 750 model only)

Serrated Grip - The textured grip provides a strong, non-slip hold, ideal for pulling pins or loosening stripped screws with ease.

V-Notch – The jaw features a small V-shaped groove for securely gripping small, round workpieces, ensuring a firm and accurate hold for detailed tasks.

Hammerhead with Mounting Hole – The built-in hammerhead offers extra utility, with a sharp edge for use as a scraper.
