Orbit blocks™ are a no-compromise product range developed to meet the demands and expectation of the very dedicated and increasingly professional racing sailor. Side cheeks incorporating head structure and hub are precision machined as a single part from solid alloy, leaving material only where it contributes to the load carrying capacity of the block and eliminating the need for additional fasteners. The Orbit sheave has captive Acetal ball bearings for side thrust loads, eliminating the need for side retainer plates. This reduces weight and allows for a wider bearing surface that can accommodate longer Torlon® needles – achieving a substantially higher strength-to-weight ratio.

Orbit Block™ – Ball Bearing
Ball Bearing Orbit Blocksï¿½ boast the highest strength-to-weight ratio available. This is achieved through all-composite reinforced polymer materials and a Dyneemaï¿½ rope link head. Their precision design allows the optimum number of ball bearings in loaded areas and eliminates them in inactive areas. Ineffective mass is reduced even further through fibre-reinforced composites in the block head, cleat arms and beckets

SHOCKS – RONSTAN SHEAVELESS BLOCKS
From simple off the beach dinghies to massive foiling multihulls, today’s yachts and the systems for rigging and controlling them are more varied than ever. This diversity creates unique demands on the hardware and is nowhere more apparent than in the category of blocks. Ball and roller bearings can still provide the lowest levels of friction, but in many applications and environments weight, strength-to-weight, durability and simplicity are the key requirements.
These applications have seen the evolution of apparently simple products, who’s outward appearance belie the exacting engineering and advances in materials technology that they are based on, and which still deliver excellent free running of lines. Custom made low friction rings and solid fairleads have filtered down from Grand Prix racing to the realm of recreational sailor.
The Torlon® Roller and Ball Bearing self-contained alloy sheave packages provide reliable, low-friction performance at high loads. The high axial loads are carried by Torlon® roller needle bearings, while side thrust loads are taken up by Acetal ball bearin
Lead blocks are a low profile solution for leading halyards or other rig sail controls back to cleats or jammers.
Small Boat Upright Lead & Pivoting Lead
UPRIGHT LEAD BLOCKS
Big Boat Upright Lead
– High static and dynamic load capacity

Wire blocks suit halyards, vang and backstay applications
Ronstan manufactures an extensive range of sheave boxes for use with rope and wire. Plain bearing sheaves are ideal for halyards and other applications where high static loads are likely to be encountered.
Ideal for applications where lines (rope or wire) need to be led through decks, bulkheads or spars minimising friction and chafing
Precision moulded Acetal sheaves running on stainless steel or Torlon® ball bearings provide high performance & low friction.
Exit blocks minimise friction in lines passing through the deck or exiting masts and booms

Deck organisers are an effective means of deflecting halyards and other control lines to winches, stoppers and cleats. Sheaves are made from impact resistant Acetal. The deck organisers have alloy cheeks, flared at rope entry and exit points to minimise chafing. All sizes can be stacked to create double versions – MWL of the top sheaves must not exceed 50% of the total block load rating.

CLEATS, CLUTCHES & JAMMERS:
THE ALLOY CAM CLEAT™
Aluminium cam models built for ultimate durability where high wear and high loads are encountered. Cams are hot-forged and hard anodised for maximum strength and corrosion resistance. Ronstan Alloy Cam Cleat™ models are available in sizes small and medium. The medium cleat is built on an aluminium base for maximum rigidity whilst the small cleat has a composite base for an optimum blend of lightness and durability.
THE CARBON FIBRE CLEAT
The lightweight ultra rigid carbon fibre composite cams of the C-Cleat are corrosion free, suffer virtually no tooth wear and are non-rope abrasive. The base is produced from long fibre reinforced polymer, a result of advanced composite technology providing metal replacement performance.
T-CLEAT CAM CLEATS
The Ronstan T-Cleats have tough glass fibre re-inforced cams and base providing outstanding value for most cleating applications.
RONSTAN V-CLEATS T CLEATS
SIMPLE BUT EFFECTIVE
Ronstan V-Cleats T are simple yet effective rope cleating devices. Manufactured from PTFE impregnated, glass and carbon fibre reinforced composite material they are lightweight, corrosion proof and provide superior wear resistance to traditional plastic cleats. Computer generated tooth geometry provides a positive, self-cleating action on the line. For applications where constant line draw-through or very high loads are the added durability of alloy Clamcleats®, or the opening action of Ronstan cam cleats are recommended.
CLAMCLEATS® CLEATS – A COMPREHENSIVE RANGE OF CLEATS AND ACCESSORIES
A comprehensive range of cleats and accessories offering simple, practical solutions for virtually any rope holding application. A deceptively simple ridged ‘V’ groove holds ropes firmly, yet is devoid of any moving parts to break or seize. It allows the immediate release of rope by a short upward and backward pull.
C-TRACK TRAVELLER SYSTEMS – STRONG & LOW PROFILE
The Series 19 is an update of Ronstan’s proven small boat track and slide systems. The brass slides of the earlier series have been replaced with glass-fibre reinforced polymer and the track is now alloy instead of stainless steel. This means the fittings are only half the weight of the earlier system but provide identical load capacities. The composite slides also have lower friction when running in the track.
The Series 27 stainless steel track is typically used on dinghies for jib sheet leads and adjustable hiking strap systems. It is also used for adjustable goosenecks and outhauls. Slides are made from chrome plated brass.
BALL BEARING TRAVELLER SYSTEMS – SMOOTH CONTROL
Ronstan traveller systems deliver the performance required for optimising sail trim, responding quickly to changing conditions and getting the right balance from the loads on sails, rig and foils. Ronstan systems have been put to the test by Volvo Race teams, Vendée Globe challengers, and the professionals on the prestige international circuits who demand the highest performance and dependability, with no room for compromise.
I-BEAM TRAVELLER SYSTEMS – SIMPLE & RELIABLE
The I-Beam series is a simple, reliable range of travellers. Strong stainless steel bodies with flared sides and angled ball bearing wheels provide high load capacity and smooth operation. Wheels and ball bearings are made of stainless steel and tracks are anodised aluminium.
T-TRACK TRAVELLER SYSTEMS – TOUGH, LIGHTWEIGHT AND LOW PROFILE
For small keel boats and sportsboats, T-Track jib lead and spinnaker pole slides are a great blend of performance and functionality in a simple, efficient package. Composite slide bodies with plunger stops run on anodised aluminium track, and allow quick and easy manual adjustment.
