20mm Dynamic Flip Flop Block with a..77 cleat

20mm flip flop block with ball bearing sheave and aluminium cam cleat.

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.
