Ronstan RF56101 Series 55 RT Orbit Block Single Link Head

Great for rapid easing of the sheet and for gybing asymmetric spinnake

Now you can enjoy the flexibility of setting up your ratchet blocks to suit yourself with the Ronstan RF56101 Series 55 RT Orbit Block Single Link Head. This automatic ratchet block features a ratchet mechanism that engages when load is applied, but switches off when it's released. This lets the sheet run out smoothly and freely - great for rapid easing of the sheet and for gybing asymmetric spinnakers.

Awesome ratchet block holding power
Quite simply, Ronstan Ratchet Orbit Blocks have the highest holding power available. The sophisticated NC-machined sheave features Generation 2 patented sheave cross-hole geometry. Its holding power is up to 21:1. The unique sheave design has 12 gripping faces which directly resist loaded line movement. The Generation 2 design has straight resistance faces which both distribute the load and minimise rope wear. These faces are offset from the radial line, to draw the rope down into the gripping area when under load.

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. The sheet runs out smoothly and freely as soon as the ratchet mechanism disengages.
