Turnbuckles & Rigging Screws

Turnbuckles & Rigging Screws

ABOUT TURNBUCKLES

Turnbuckles originate from the Aircraft Industry, where they have historically been utilised for tensioning structural wires for aircraft wings - perfectly illustrating the structural integrity of these products.

Rigging Screws and Turnbuckles are seen as one of the quickest and most effortless means of tensioning your cable and wire ropes. Tension is adjusted by simply turning the main-frame to increase or release the strain of the cable/rope. This is ideal in multiple applications where you wouldn't have to twist either the eye bolts or the cables -  a painless operation that cuts out the trivial process of removing cables and restraining the load in order to gain the correct tension for the application.

The main difference between a Turnbuckle and a Rigging Screw is that a turnbuckle features an open body, meets US standards, and is measured imperially in inches. In contrast, Rigging Screws is designed with a closed body and are measured metrically in millimetres.

WHAT ARE TURNBUCKLES AND RIGGING SCREWS?

A turnbuckle, also known as a rigging screw or bottlescrew, is a device that is used to eliminate slack or adjust the tension of a rope, cable or other type of attached tensioning system. They are typically made up of two threaded eye bolts, each screwed into the one of two ends of a small metal frame, one with a left-hand thread and the other with a right-hand thread. 

ARE RIGGING SCREWS AND TURNBUCKLES THE SAME THING?
A rigging screw and a turnbuckle are two terms that are used interchangeably to refer to the same piece of equipment. The usage of the two terms may differ by regional dialect, or by the type of industry, however the term “turnbuckle” tends to be more commonly used.
