A half coupler factory fitted with a Rud Pink Eye. The high tensile extruded aluminium clamp is suitable for 48mm to 51mm diameter tubes and is 50mm wide. The Pink Eye is an articulated M12 Eye Nut with a WLL of 750Kg. It is manufactured from high tensile forged materials and annealed. This product is 100% electromagnetic crack detected in accordance with EN 1677-1. Unlike standard eye nuts, the Pink Eye can be used in unfavourable load directions (not permissible for DIN 580). Please note that although the eye is designed to spin 360 degrees to get it in the correct position it is not designed to turn under load as this can lead to the bolt loosening.
