Ronstan RF46100 Series 40 RTA Orbit Block Auto Single Swivel Head

Now you can enjoy the flexibility of setting up your fitout exactly to suit yourself. With the Ronstan RF46100 Series 40 RTA Orbit Block Auto Single Swivel Head, the ratchet mechanism 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 of our patented sheave cross-hole geometry. The Series 40 delivers up to 14:1 holding power.

Unique sheave design has 8 gripping faces which directly resist loaded line movement
Traditional designs have an angled resistance to 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 carbon connection points - much more so than steel loop tops or shackles.

Smooth easing of sheets
With auto models the sheet runs out smoothly and freely as soon as the ratchet mechanism disengages. When engaged, the sheave cross - hole geometry eliminates the 'shuddering' ease-out that you can expect from traditional v-groove ratchet blocks.

Low profile stand-up kit allows 0 or 90 degrees alignment
Stand-up kits feature a clatter-free rubber boot. You can attach the Dyneema link so that the block is aligned with the stand-up base or across it. It's a neat low-profile solution which allows full articulation.
