The Award Winning CL815 Keeper has been designed to overcome the problem of lines being cleated accidentally as well as improving performance by holding lightly-loaded lines in the jaws of a cleat when mounted upside down. When using a cleat fitted with a Keeper, the operation and performance is completely transformed. The lead-in makes cleating a line easier and there is a satisfying and positive click as the line is released or cleated.
