Open turnbuckle | jaw/jaw | A4 | M8021
Turnbuckle, also known as a stainless steel wire tensioner (A4), is designed for use in corrosive and marine environments. The product is used where stepless length adjustment and controlled tensioning of wire, cable, or stays are required. Its design allows for precise fine-tuning of tension and length without disassembling the connection. It is suitable for installations where high corrosion resistance, reliable function, and long service life are essential.
AREA OF APPLICATION
The product is used in marine rigging, wire systems, railing installations, building structures, and outdoor environments. It is intended for applications where adjustable wire tension, re-tensioning, and precise length adjustment are required, for example in cable railings, guy wires, antenna masts, and load-bearing wire structures. The material provides resistance against saltwater, moisture, and chemically aggressive environments.

FREQUENTLY ASKED QUESTIONS (FAQ)
What is a turnbuckle and how is it used?
A turnbuckle (also called a wire tensioner or rigging screw) is used for re-tensioning and fine-tuning the load in wires, chains, and steel cables. It consists of a central body with opposing threads (right-hand and left-hand thread) that pull the end fittings towards each other when the body is rotated.
What does it mean that the turnbuckle is made of acid-proof A4 stainless steel?
Acid-proof stainless steel in grade A4 (equivalent to AISI 316 / 1.4401) contains molybdenum, which provides exceptionally good resistance to corrosion. This makes the turnbuckle suitable for use in demanding environments such as marine environments, coastal areas with salt spray, pool areas, and the chemical industry.
How do I choose the right size and end fitting for the turnbuckle?
The choice of size is determined by the diameter of the wire and the tensile load the turnbuckle needs to withstand. Regarding end fittings, choose eye for permanent or locked attachments, hook for quick and easy detachment, or jaw for direct attachment to plates, eyelets, and clevis pins.
