U clevis
U clevis, also known as an anchor shackle or clevis fastener, is a U-shaped metal fastening device used in overhead line systems and electrical installations. This component features a U-shaped body with holes at the end of each prong, designed to accept a clevis pin for secure connections. The clevis is typically manufactured from high-strength steel or malleable iron and hot-dip galvanized to ensure durability and corrosion resistance. It serves as a crucial connecting element in various electrical applications, particularly in transmission and distribution systems.
The U clevis is designed to work seamlessly with multiple components including thimble eye nuts, guy grips, dead-end clamps, and insulator assemblies. Installation involves inserting the clevis pin through the aligned holes of both the U clevis and the connecting component, then securing it with a cotter pin or lock nut. This creates a strong, reliable connection point that can withstand significant mechanical loads while allowing necessary movement in the system.
Key Features:
– Load capacity: 70kN for standard models
– Material: Hot-dip galvanized steel or malleable iron
– Pin diameter: 16mm or 20mm standard sizes
– Working temperature: -40°C to +85°C
– Compatible with guy wire sizes: 7/16″ to 5/8″

Frequently Asked Questions
What is a U Clevis?
What is a U Clevis?A U clevis is a D-shaped pole line accessory used for connecting components in utility applications, particularly for attaching spool insulators to utility poles.
What are the main components of a U Clevis?
The main components include:
- The U-shaped clevis body
- Clevis pin
- Cotter pin

How strong is a U Clevis compared to other fasteners?
A U clevis pin is typically stronger than a standard bolt because it fills the entire diameter of the hole. For example, while a clevis pin for an 8mm hole utilizes the full 8mm diameter, an M8 bolt only has a 6.65mm core diameter.
What are the primary applications in utility systems?
- Connecting spool insulators to poles
- Balancing strains at corners
- Providing attachment points for conductors
- Minimizing turning resistance in overhead lines
Are U Clevis pins hardened?
Yes, U clevis pins are typically hardened to ensure durability and maintain structural integrity under load conditions in utility applications.
