ClamCleat® Aluminum Open Starboard ø3 to 6mm : This clamcleat is ideal in situations where a complete release of the line is necessary, or when the use of the jammer is temporary . The side-entry line guide (starboard side) allows lines or ropes to be attached for securing, while also allowing for easy removal. This cleat is found on removable lines that are installed and removed before and after sailing: it is used on Laser tillers to secure the rudder and tiller.
