Product information "DT PRO Narrow Clamp 500kg Stainless A4"

The Duratruss DT Pro Narrow Clamp Stainless A4 is a robust, narrow coupler made from maritime-grade A4 stainless steel, designed for use in highly corrosive environments. Whether on cruise ships, in shipyards, open-air beach clubs, indoor swimming pools, or any location where A4 stainless steel is required, this clamp ensures safe and reliable truss mounting for professional applications.

A4 stainless steel offers outstanding corrosion and acid resistance: with approximately 2% molybdenum added to the alloy, it provides significantly better protection against pitting and corrosion than standard A2 stainless steel. The clamp is ideal for chloride- and salt-containing environments such as seawater and swimming pools, as well as for certain acids. Its excellent weather resistance makes it perfect for outdoor use, especially in coastal areas, where it remains rust-free even under harsh conditions. In addition, the DT Pro Narrow Clamp A4 covers a wide temperature range and can be used reliably at temperatures down to around -60 °C.

With its compact design and high safe working load of up to 500 kg, it is the ideal solution for secure and flexible installations of trusses, luminaires and other stage or event equipment in demanding environments.
