More information on Clamcleats® :
Sailing Clamcleats use a simple v-shaped groove with ridges or 'teeth' to hold lines securely on dinghies, catamarans and other small boats. Easy to cleat or release with a quick pull, Clamcleats work well to securely hold control lines or small halyards. Made to cleat lines 16mm and smaller.
APS stocks the right clamcleat for any application.
Open Clam Cleats allow the rope to drop down straight into the teeth of the cleat to secure it.
Fairlead Clamcleats guide the rope into the cleat through the fairlead at the front of the cleat.
Side Entry Clamcleats use a side entry fairlead allowing the rope to be hooked under the fairlead and cleated.
Roller Clamcleats use a roller to allow ropes to smoothly enter the cleat at angles greater than traditional clam cleats. Reduced friction compared to a fairlead clam cleat means these are great for frequently adjusted lines.
Power Grip Clamcleats create a handle of sorts allowing you to pull at least twice as hard without the pain of pulling on smaller diameter line.
Auto Release Clamcleats are designed to be mounted on the tiller for easy release of the rudder when a set load is exceeded (such as hitting underwater objects or bottom). The auto release clam cleat is great for dinghies or any boat with a swing up rudder assembly.
Sail Line Clamcleats are attached to the sail and perfect for tensioning leech lines or to adjust reefing points on sails.
Clamcleats Rigged on a Line are used as trapeze and vang cleats. This cleat has a built in pulley for a quick, secure lock that is easy to release.
