Our High Strength Preformed Guy Wire Clam is engineered as a premium termination/anchoring device for guy wires (stay wires) used in utility, telecommunication, tower and pole‑line infrastructure. It features pre‑formed helical wrap design that securely grips the guy strand without the need for welding or bolting, ensuring reliable mechanical connection under high tension loads and harsh environmental conditions.
The device is manufactured from high‑grade steel wire (or other specified alloy) with durable galvanised finish (or alternative coating) for excellent corrosion resistance. Designed for ease of installation and optimum performance, the guy wire clam provides a safe, efficient and cost‑effective anchoring solution for high strength guy systems.
Here are the principal benefits of our High Strength Preformed Guy Wire Clam:
The helical pre‑formed design allows for full rated breaking strength of the strand to be utilised (many comparable products are rated at 90‑100% of the strand’s published breaking strength).
This ensures that the anchor/clamp does not become the weak point in the guy system.
The spiral legs wrap around the strand, distributing the load over multiple wraps and minimising stress concentration, providing reliable grip even under dynamic loading (wind, vibration).
Made from high‑quality steel wire (and/or stainless/Al‑clad steel according to application), hot‑dip galvanised (and/or special coating) for long service life in outdoor conditions.
Pre‑formed design eliminates the need for tools, clamps or welding; installation is quicker and safer, reducing labour time and cost.
Available for a range of strand sizes, constructions (7‑wire, 19‑wire, EHS etc.), and can be customised (length, material, coating, colour‑coding) to suit specific project needs.
Reliable anchoring in diverse structural settings
Suitable for utility poles, communication towers, transmission line guy systems, offshore/marine installations, etc. Ensures stability of the structure by terminating and anchoring guy wires effectively.
Our High Strength Preformed Guy Wire Clam finds application in the following scenarios:
Anchoring guy wires for utility poles (distribution and transmission) to resist lateral loads from overhead conductors.
Securing stay wires for telecommunication masts, broadcast towers, monopoles and lattice towers.
Supporting structures in renewable energy installations (wind turbine towers, solar support frames) where guying is required.
Marine and offshore platforms where guy or stay wires are used and corrosion protection is critical.
Any scenario where high‑strength guy wire termination is required: bridge supports, antenna installations, temporary structures, scaffolding stay systems, etc.
Replacement of traditional dead‑end clamps or hand‑tied terminations, offering improved reliability and easier installation.

Q1: What is the difference between a guy clamp (clam) and a pre‑formed guy grip?
A1: A guy clamp typically refers to a bolted or mechanical clamp device that grips the guy wire via pressure. A pre‑formed guy grip (or “dead‑end”) uses helical wire legs that wrap around the strand and rely on the pre‑formed geometry to provide grip without separate fasteners. The latter generally provides better load distribution, quicker installation and fewer stress points.
Q2: What installation considerations are there?
A2: Key points include: (a) matching the lay (right or left) of the guy strand, (b) ensuring the device is the correct size and rated for the application, (c) following proper spiral wrap procedure or manufacturer’s installation guide, (d) verifying that supporting hardware (eyes, turnbuckles, shackles) is compatible and smooth to avoid strand abrasion.
Q3: What about corrosion and service life?
A3: Because guy wires and anchors are exposed to outdoor elements (rain, salt spray, wind), the material and finish of the clamp are critical. Our product uses high‑quality steel wire with hot dip galvanised or similar protective coating, ensuring long life and stable performance in harsh environments. For marine or extra‑corrosive environments, stainless steel or aluminium‑clad steel options are available.
Q4: What are typical application loads or environmental uses?
A4: These clamps are widely used in power transmission/distribution guy systems, telecommunication towers, antenna masts, offshore structures, temporary scaffolding/stays, and more. They handle high tension loads, dynamic loading (wind, vibration) and long‑term installations.
