Spool Bolt

Product Overview

Spool insulators used in secondary distribution systems require dedicated fastening components to secure the insulator assembly to utility poles and supporting structures. A spool bolt provides the mechanical attachment point between the insulator and the pole-mounted hardware system.

The Reacon ASTM A153 Hot Dip Galvanized Spool Bolt is designed for spool insulator mounting applications in overhead distribution networks. It is commonly used in low-voltage and secondary distribution construction where spool insulators are installed for conductor routing and support.

Manufactured from steel and protected by a hot dip galvanized coating in accordance with ASTM A153 requirements, the bolt is suitable for outdoor utility environments.

Focus on Spool Insulator Installation

Unlike lag screws used for attaching brackets directly to wood poles, a spool bolt is specifically used to secure spool insulators and related hardware assemblies.

This application helps:

• Support insulator mounting

• Maintain conductor routing positions

• Simplify pole hardware assembly

• Facilitate maintenance and replacement
  

Because of these functions, spool bolts are commonly specified in secondary distribution and service line construction projects.
