Hot Dip Galvanized Dual Hook Steel Turnbuckle — 5-100kN Adjustable Tensioning for Guy Lines and Support Cables
Supplied by Suntech Power Tools, a Ningbo-based manufacturer with more than 20 years of experience in power transmission line stringing and utility hardware, this dual hook steel turnbuckle is a precision tensioning device used to adjust, tighten and secure guy wires, support cables and structural braces in power construction.
Product Overview
By rotating the central barrel, the two hook ends are drawn together or extended apart, shortening or lengthening the assembly so field crews can achieve the exact tension required — whether for initial installation, seasonal adjustment or corrective maintenance. This makes the turnbuckle indispensable for maintaining the stability, alignment and safety of utility poles, transmission towers and substation structures over their full service life.

Key Features & Benefits
- Precise in-field tension adjustment: Rotating the central body draws the hook ends together or apart for fine-tuned control of cable and wire tension.
- Secure hook-to-hook connection: The closed hook design fits thimbles, shackles and eyes snugly, preventing accidental disengagement.
- High strength and load capacity: Forged and high-tensile steel construction withstands demanding tensile loads from wind, ice and conductor weight.
- Corrosion resistance for outdoor use: Hot-dip galvanizing forms a robust barrier against rust caused by moisture, salt and industrial pollutants.
- Easy installation and maintenance: The barrel accepts a lever or bar for quick turning, streamlining field adjustment.
- Long service life: Once installed and tensioned, galvanized turnbuckles require virtually no maintenance.
Applications
- Guying systems for utility poles and transmission towers
- Tensioning overhead ground wires and support cables
- Substation structure bracing and alignment
- Temporary structural bracing during construction
