Messenger Hanger Bracket
A Messenger Hanger, also known as a Messenger Hanger Bracket or Cable Support Bracket, is a specialized hardware component designed for supporting aerial cables and messenger wires in utility networks. Made from hot-formed, high-quality steel with hot-dip galvanized coating, these hangers feature a specially curved groove that accommodates both corner installations and straight runs. The design includes independent clamping mechanisms that ensure the messenger remains securely clamped even if pole shrinkage occurs.
These hangers are essential in telecommunications and power distribution networks, providing stable support for various cable configurations. Installation involves mounting the bracket to poles or standoff brackets, with vertical fingers supporting the cable during the stringing operation. The hangers can accommodate messenger wire ranges from 5/16″ to 1/2″, featuring curved grooves for enhanced cable support and upward-kicking lips that assist during installation. They work seamlessly with other line hardware components to create a complete overhead cable support system.
Key Features:
- Hot-dip galvanized steel construction for durability
- Curved messenger groove for better support on corners and straight runs
- Independent clamping system unaffected by pole shrinkage
- Vertical fingers for cable support during installation
- Compatible with various mounting surfaces (round or flat)
- Belled groove ends for improved angle installations
