Guy Wire Strandvise
A strand vise, also known as an automatic guy wire deadend or guy wire strandvise, is a cone-shaped device designed for terminating guy wires and overhead cables. The structure consists of a cartridge, yoke, and bail, utilizing a finger-trap principle where spring-projected jaws grip the cable. The strand vise features galvanized steel construction for durability and chemical resistance.
The strand vise can accommodate various wire sizes from 3/8″ to 1/2″ and works with different strand types including alum weld, galvanized, aluminized, and EHS steel strand. Installation is straightforward – simply insert the guy wire through the narrow end of the cone, allowing the jaws to automatically grip and establish a secure connection. The strand vise requires no nuts or torque compression, making it efficient for both overhead and down guy wire applications.
Features:
• Supports 90% minimum of rated breaking strength
• Universal bale design for multiple wire sizes
• Cone-shaped structure ensures tight grip
• Simple tool-free installation process
• Galvanized steel construction for outdoor use
• Compatible with various steel strand types

Frequently Asked Questions (FAQ)
What sizes of wires does a strand vise support?
Strand vises are designed to accommodate different wire sizes, typically ranging from 3/16″ to 1/2″. However, it’s important to check the specific product specifications to ensure compatibility with your strands. Some models may support wire ranges from 0.185″ to 0.392″ in diameter.
What materials are strand vises made of?
Strand vises are typically made of galvanized stainless steel, providing high physical and mechanical strength suitable for outdoor applications. The galvanization protects the vise from rust and chemical destruction, making it durable in various environmental conditions.
How much load can a strand vise hold?
Most strand vises are rated to hold a minimum of 90% of the Rated Breaking Strength (RBS) of the approved strands. This makes them suitable for most applications, providing a secure and reliable connection for guy wires.
How do you install a strand vise?
To install a strand vise, simply insert the guy wire through the narrow end of the cone-shaped device. The internal jaws will automatically grip the wire, establishing a strong connection. No special tools are required, making installation quick and easy.
Can strand vises be reused?
While strand vises can be released using a flat-blade screwdriver to relieve spring tension, they are generally not designed for frequent reuse. The gripping mechanism may wear down after multiple uses, potentially compromising its holding strength.
Are strand vises suitable for tower guys?
While strand vises are commonly used on utility poles, they are less frequently seen on towers. This is partly due to the potential need for re-tensioning guy wires, which is easier with traditional cable clamps and thimbles. However, strand vises can be used effectively with strain insulators on towers.
What types of strand are compatible with strand vises?
Strand vises are generally compatible with various types of strand, including Alumoweld, Extra High Strength (EHS) galvanized steel, common grade, Siemens-Martin, high-strength utility grade, aluminized, and galvanized steel strand. Always check the manufacturer’s specifications for specific compatibility.
In what industries are strand vises commonly used?
Strand vises find applications in power transmission and distribution, telecommunication towers, wind energy systems, antenna mast guying, structural guying for bridges and tall buildings, and communication and broadcast towers. They provide secure termination and adjustable tension for guy wires in these industries.
