Ronstan Series 55 RT Orbit Block, Cheek, Clockwise Rotation
$78.12
Multiple gripping faces machined into our ratchet block sheaves work
in conjunction with our 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.
It is essential equipment on racing dinghies and sports boats, and when you want the ultimate holding power.
- Manual, Auto and Auto+Manual blocks.
- Awesome ratchet block holding power.
- Simple and secure attachment.
- Smooth easing of sheets.
- High performance cleating.
