SP58 Stainless Steel Ground Rod Clamp

Description

SP58 Stainless Steel Ground Rod Clamp

The SP58 Stainless Steel Ground Rod Clamp, part of the ERITECH® line of products from ERICO, is made from a non-rigid stainless steel metal strip, which will not crack when excessive torque is applied during installation. The innovative design and material allow the SP58 to conform around the ground rod and conductor as the bolt is tightened, increasing the conduction area of the connection.

The one-piece thread insert provides a clean internal thread profile with a tighter thread pitch, which creates stability and improves performance. If over-tightened, the bolt head is designed to shear, making a secure connection instead of stripping or cracking like a traditional acorn clamp.

This versatile clamp is designed for many assembly combinations: #10 solid through #2 stranded (6 mm2 – 25 mm2) conductor to 1/2″ thru 5/8″ (12.7 mm – 16 mm) ground rods, or a #4 (10 mm) rebar and other solid 5/8″ (16 mm) metal rods that can be used as grounding electrodes. The stainless steel ground rod clamp is compatible with many types of ground rods and electrodes, including but not limited to copper, copper-bonded, galvanized, stainless steel, rebar and plain steel rod. The patent-pending, UL® Listed SP58 clamp is more resistant to corrosion than a bronze acorn clamp, and is approved for direct burial.

Features

  • Conforms around the ground rod/electrode after the bolt is tightened
  • Provides a greater surface area contact to allow improved performance of the connector
  • Unique stamped body design will not crack with excessive torque values
  • Compatible with copper, copper-bonded, galvanized, stainless steel, rebar and plain steel ground rods and electrodes
  • cULus® Listed*
  • Patent pending

Applications

The SP58 stainless steel ground rod clamp is ideal for use with many types of ground rods and electrodes, including but not limited to copper, copper-bonded, galvanized, stainless steel, rebar and plain steel rod.
