Ronstan Orbit cheek block 55 mm. ratchet linksom

Automatic and Manual ratchet in one block Up to 20:1 holding power Smooth easing of sheets High performance cleating . 1 Simple and secure attachment The Dyneema® Link is easily fitted and is retained securely by a moulded retainer clip. The flexible link can be left with one end attached to the block when fitting - no more lost shackle pins. The system is compatible with Dyneema®/Spectra® strops, webbing and caron connection points - much more so than steel loop tops or shackles. In auto mode, the sheet runs out smoothly and freely sas soon as the ratchet mechanism disengages. In manual mode, the sheave cross-hole geomtry eliminates the 'shuddering' run-out that you can expect from traditional v-groove ratchet blocks.
