If you are looking for flexibility and performance in your dinghy or sportboat mainsheet cleating system, include Ronstan's RF7 Swivel Arm Base with a C-Cleat and Adjustable Ratchet. Not only does it have a swivel cleat base that can rotate the cleat arm 360ﾰ or be limited to 260ﾰ, it has an adjustable ratchet system that prevents the cleat arm from falling to leeward. Its fork fitting has a 3/16 in (5mm) pin that accepts the direct attachment of a block's head post. This eliminates the need for a shackle attachment. The cleat works with line under 15/32 in (12mm). This base does not come with a block, however it suits traditional post/shackle head blocks and Dyneema Link head Orbit Blocks.
