The AnchoRight anchor chain markers are the ideal solution for safe and easy labelling of your anchor chain. They offer a number of advantages over conventional markings. The colour guide frame is an optional addition to the anchor chain markers. It offers a simple and clear way to position the markings. The frame can be attached anywhere on the deck or in the cockpit. The included screws are seawater resistant and ensure a secure attachment. The installation of the chain markers is very easy. All you need is a small Phillips screwdriver. To attach the markers, break off the two opposite halves of the marker from the holder. Then insert the two halves into the chain link from both sides. One half has a protrusion, the other has a recess and a screw hole. Press the two halves firmly together to ensure they are aligned. Then insert the included screw into the hole and tighten it with the screwdriver. To create the colour guide frame, insert the numbers and colours into the plate in the desired order. The numbers are on one side of the plate, the colours on the other side. We recommend using the anchor indicator as the first marked point. This should be placed about 1 metre above the anchor. The stop marker should be attached to the end of the chain to indicate when the winch should be stopped. Then attach the frame anywhere on the deck or cockpit.
