This flip flop cleat comes with a detachable 30mm sheave and is made for easy and efficient use. Designed with a central fixing point, it keeps the rope close to the deck, mast, or boom while still allowing for the correct lead angle. This lightweight version features a nylon body and backing plate to minimize weight and cost. Its 30mm dynamic sheave is equipped with twin rows of stainless steel ball bearings for superior load-carrying and durability. In addition, the A.677 small Allenite cam cleat is made with a special material that reduces weight and dissipates heat for increased wear resistance. This cleat is perfect for lower loading halyards, pole launchers, and jib sheets, while higher loading applications may require the A2133-77.
