steelthrough-hole

The innovative 3+ Backing Ring combines lightness with an exceptional mechanical resistance thanks to its optimized design. Pins inside holes and guided tightening sequence make installation simple, safe and reliable. They are available from d20 to d315, DIN drilling. The name 3+ stands for three unique pluses: 1. Lightness: Lightweight product and best in class performances due to the patented wedge shape profile of the metal core and the PP-GR coating ensuring chemical and corrosion resistance. 2. Mechanical Resistance: Optimized and enhanced thanks to its new design that allows an excellent breaking load, outstanding elasticity properties and durability over time. 3. Ease of Installation: Thanks to the bolts tightening sequence indications and to its symmetricity that allows bi-directional installation. This product is EPD verified and has therefore a lower environmental impact. Thanks to this new design, C02 emissions have been reduced by 20%
