Description
Gilray Plant’s drop-forged scaffold double couplers are tested to EN74-1 and are independently audited by the National Access & Scaffolding Confederation (NASC). These double coupler fittings are part of our full range of scaffold fittings. These include swivels, wrapovers and sleeves. All these fittings are descendants of the “Scaffixer”.
In the early part of the 20th Century, the modern era of scaffolding began when Daniel Palmer Jones developed the system of Tube & Fittings (T&F). Palmer Jones patented the “Scaffixer”. This extraordinary and relatively simple item was a coupling device far more robust than rope. This coupler revolutionized scaffolding construction and enabled the building of skyscrapers. In 1913, his company won the commission for the reconstruction of Buckingham Palace. Due to this contract, his Scaffixer gained much publicity.
Palmer-Jones followed this up with the improved “Universal Coupler” in 1919. This coupler soon became the industry standard coupling and has remained so to this day. The basis of this system has not changed. Scaffold tubing of various lengths is connected together by the use of different types of coupler to form a complete structure. Of course, there have been many refinements and improvements in safety over the years, but the principles of “tube & fittings” scaffolding have not changed. Indeed, nd it is still the major form of scaffolding in use worldwide!
