Ronstan Orbit Ratched Blocks


Awesome Holding Power

Multiple gripping faces machined into the ratchet block sheaves work in conjunction with a unique cross-hole geometry, delivering up to 20:1 holding power to resist slipping of the loaded line while minimising rope wear.

Ball bearings ensure minimum friction under load and a free running sheave when the ratchet is disengaged. Control switches are located on both sides of the block to remain accessible wherever the block is fitted. In auto mode, the ratchet mechanism engages when load is applied but disengages when released to let the sheet run out freely – ideal for gybing asymmetric spinnakers. In manual mode, the switch is used to set up the block with ratchet either on or off as required.
