Anchor rollers make dropping and weighing anchor easier on you and your boat. They help reduce chafe, prevent scratches and dings to your boat?s finish and provide a secure place to store your anchor when used in conjunction with an optional chain stopper or tensioner. We stock rollers to fit the most common combinations of anchor, mounting style and boat. Installation note: overhanging anchor rollers should be supported along at least 2/3 of their length.
