Lightweight Flip Flop Cleat with removable 30mm Sheave.
Flip flop blocks are designed to pivot around a central fixing point, this keeps the rope close to the deck, mast or boom whilst still allowing the block to articulate to the correct lead angle, ensuring friction stays as low as possible whilst still guiding the rope to where it needs to go.
This lightweight version has a nylon body and nylon backing plate to keep weight and cost to a minimum.
Features a 30mm dynamic sheave. Which uses twin rows of stainless-steel ball bearings running on a stainless-steel rail. This provides a superior load-carrying ability and longevity when compared to other bearing systems which run on a plastic rail.
Also featured is the A.677 small allenite cam cleat. Allenite is a material developed by Allen specifically for low weight and good heat dissipation to increase wear resistance over standard acetals. The Allenite cam cleat offers a good weight saving over the aluminium version.
Ideal for lower loading halyards, pole launchers and jib sheets. Higher loading applications should use the A2133-77.
