![]() Why Choose Dura International’s Drop Forged Double Coupler?ĭura International manufactures and supplies BS1139 and EN 74 standard scaffolding couplers, which act as connectors between scaffold tubes. The typical working load limit of double couplers is 6.25kN (637.32 KGF) against slip at tightening torque of 54Nm. Always opt for one that features a hot-dip galvanised finish such as that manufactured by Dura Internationalto take full advantage of its corrosion resistance. They are manufactured in such a robust design that are able to deliver optimal durability and reliability. They come with tightening nuts that meet the standards of the Scaffold Spanner (23mm A/F) with the ‘T’ bolts, nuts and washers being replaceable. Getting to know the load-bearing capacity of the scaffolding and access systems helps ensure the safety of workers and bystanders in the work site.ĭouble couplers have an outside diameter of 48.3 mm at right angles. Sizeable accidents are prone to happen when the scaffolding structure you opted for doesn't meet your purpose. Double Coupler Capacity - What is the Safe Working Load? The latter is also termed the Layher scaffold double coupler, a relatively strong duty scaffold drop-forged right angle clamp. There exist two types of German scaffold double coupler : normal threaded and round threaded. Thanks to their excellent slide and damage resistance, double couplers are amongst the widely used heavy-duty, anti-slipping forging scaffolding couplers in Germany as well as other countries. They also work well in resisting tension or compressive loads. Joining scaffold tubes in 90 degrees, these right angle connectors are designed for use in various types of scaffolding construction including in lighting rigs, staging and guard rails.ĭouble couplers have a safe working load of 6.1kN, making it ideal for use on a ledger, standard, transom or brace. What are Double Couplers in Scaffolding?Īlso referred to as fixed clamps, double couplers are a type of scaffolding coupler that can be connected to a tube, either electro-galvanised or zinc-plated, in pressed or drop forged versions. All in all, they are responsible for maintaining the scaffold’s stability. Scaffolding couplers carry a multitude of uses such as the initial fold or bending of the bars, load eccentricity, and many others. They are designed to join two scaffold tubes at a different angle to ensure proper connection and installation of the scaffolding at the work site, and to offer friction between the connector and the steel pipe to transfer the weight load from one place to another. Scaffolding couplers are an integral part of scaffolding where they are primarily used to assemble tube and coupler. ![]() All GARNET SAND ABBRASIVE SUPPLIER MALAYSIAĪ Brief Overview of Double Coupler and Its Capacity.GARNET SAND ABBRASIVE SUPPLIER MALAYSIA.
