The H-Lift Commercial Type Turnbuckle is an economical tensioning device engineered for static rigging assemblies and light construction projects. Its open-frame design facilitates immediate visual inspection of thread engagement, allowing for precise length adjustments in non-critical applications such as fencing, guy wires, and agricultural support systems. This component serves as a cost-effective alternative to forged hardware for stationary loads.

Constructed from malleable iron with an electro-galvanized finish
Available configurations: Hook & Hook, Hook & Eye, and Eye & Eye
Working Load Limit (WLL) ranges from 100kg (6mm) to 3000kg (24mm)
Strictly prohibited for overhead lifting or dynamic suspension tasks
Compatible with standard commercial-grade wire ropes and chains

Technical Data
Differene between Rigging Screws and Turnbuckles

H-Lift Commercial Type Malleable Turnbuckles are the economical choice for general-purpose rigging. Manufactured from cast malleable iron with an electro-galvanized finish, these tensioners are specifically designed for light-duty, static applications such as gardening, fencing, and shade structures where high-strength forged fittings are not required.

Commercial Malleable Turnbuckle Hook and Eye

💰 Cost-Effective Solution

An economical alternative to drop-forged steel turnbuckles, perfect for non-critical applications like catenary wires and garden trellising.

🛡️ Corrosion Resistance

Features an Electro-Galvanized (Zinc Plated) finish that provides a protective barrier against rust and weathering in outdoor environments.

🔗 Versatile End Fittings

Available in Hook & Eye (most common), Eye & Eye, and Hook & Hook configurations to suit various connection points and installation needs.

📏 Metric Sizes

Stocked in a full range of metric thread sizes from 6mm to 24mm (M6 - M24) with body lengths up to 350mm.

Q: What is the difference between Commercial and Drop Forged turnbuckles?
A: Commercial turnbuckles are made of malleable iron (cast) for light, static loads. Drop Forged turnbuckles are hammered steel, significantly stronger, and suitable for heavy lifting and critical rigging.

Q: Can I use commercial turnbuckles for lifting?
A: No. Commercial malleable turnbuckles should never be used for overhead lifting. They are intended for tensioning static loads only.

⚠️ USAGE WARNING

This product is designed strictly for static tensioning (e.g., fencing, guy wires). DO NOT USE FOR OVERHEAD LIFTING or safety-critical rigging applications. For lifting, please use our Drop Forged Turnbuckles (DIN 1480 or US Fed Spec FF-T-791b).

Rigging screws and turnbuckles are essential components used to adjust tension and secure loads. While they serve similar functions, their distinct designs make them suitable for specific applications.

Rigging Screws

*Rigging screws feature a pipe-like closed body encasing the threads.

Definition: Also known as rigging tensioners, these devices adjust tension in cables, wires, or rods. They typically feature a closed body (tubular) design.
Functionality: Rotating the body causes the attached fittings (different handed threads) to move in or out, providing precise tensioning.
Best Use: Critical for maintaining correct tension in shrouds, stays, and guard wires where protection of the threads is beneficial.

Turnbuckles

*Turnbuckles feature an open frame allowing view of the threads.

Definition: Often called bottlescrews, these mechanical devices consist of an open frame with two threaded ends connected to eye bolts, hooks, or jaws.
Design: The open body allows for easy visual inspection, lubrication, and maintenance. Available in stainless steel, bronze, and galvanized steel.
Functionality: Features one left-hand and one right-hand thread. Rotating the central frame adjusts both ends simultaneously.
Applications: Widely used in marine rigging, construction, and general tensioning.

Key Differences Summary

Body Design Rigging screws generally have a closed (tubular) body, protecting the threads. Turnbuckles have an open body, allowing for inspection.
Thread Types Rigging screws typically use different handed threads on each end for fine adjustment. Turnbuckles use standard LH/RH threads for rapid adjustment.
Usage Context Turnbuckles are preferred where frequent adjustments and inspection are needed. Rigging screws are often preferred for permanent installations where aesthetics or thread protection is prioritized.
