Made from hard anodised aluminium, KOHLHOFF LOOP® Organisers are lightweight, strong, easy to install and provide a highly flexible deck organising solution. There is no issue if you want to add an additional halyard or control line, simply add in an additional fairlead where you need it. Choose between two different sizes (for 12 or 16mm max rope diameter) and two different styles (bolt or blind thread) and get organising! This 16mm Double fairlead is the base unit i.e. provides x2 ends and is fastned with x3 M8-DIN 912 bolts (not supplied). To add additional fairleads to this base unit - use the 'LOOP® Organiser - 16mm Single fairlead insert ' (L-LO18-35AO) and each additional insert requires x1 additional M8-DIN 912 bolt (not supplied).
