    Product Description


     

    Features:
    Class leading performance and sleek, contemporary styling
    Excellent dynamic and high static load performance
    Less than half the friction of the nearest competitor
    Removable becket pin for fitting of pre-spliced lines
    ** Line load through cleat not to exceed 175kg (385lb)

    Core Blocks™ are a true all round solution. A tuned 2-stage bearing system provides excellent performance across the full working load range with an integrated thrust bearing feature and the resilience to handle high dynamic or static loads. Acetal sheave, alloy cheeks and stainless fixings complete the durable package. For reliability and a long service life, these blocks are the right choice for sheets, halyards and control line applications for cruising and racing.

    Universal Bearing -
    Dynamic and high static load performance
    The Ronstan Universal Bearing incorporates our proven 2-stage bearing system
    Stage 1 - Under moderate loads, Acetal ball bearings ensure minimum friction.
    Stage 2 - Under heavy loads, where deformation of ball bearings alone would result in increased friction, a sliding Acetal bearing on a polished stainless steel race takes over, maintaining low friction performance.
    Additionally the ball bearings are configured to act as a thrust bearing between the sheave and cheeks, preventing the sheave from rubbing on the cheeks and causing friction when the line lead in and out of the block isn’t perfect. Particularly important for cheek blocks.

    Alloy cheek plates Block cheeks are manufactured from the highest quality alloy for maximum strength. Material optimisation and the cut-away design minimises weight and allows easy fresh water rinsing of salt and debris from the bearings. Cheek design has been further styled with flaring at the block throat and reduced gap between the cheek and sheave, minimising rope wear. Applications
    Ideal for mainsheet, halyard and spinnaker sheet applications on boats to 12m (40ft).
    Various control line applications on larger yachts.
    Alloy sheave models are available for use with wire.

    Materials:
    Sheave: U.V. stabilised Acetal or anodised aluminium (AW models)
    Cheek plates: Aluminium alloy
    Ball Bearings: High compression strength carbon black Acetal

    Product Description

    Intensive development efforts have produced this range of cleats that provide unbeatable holding power, yet are designed for easy cleating and releasing of control lines in every application and load condition. Through the use of advanced composites, these cleats achieve superior performance while overcoming the limitations of metal alloys. Ronstan cam cleats are strong, light and corrosion free. The unique tooth profile and cam geometry are designed to grip without damaging the rope. A multi-coil spring recessed in the upper part of the cam generates near constant torque. This constant torque ensures secure cleating of even the smallest lines with minimal abrasion or rope wear and low line entry and exit efforts. 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.

    • Design, materials selection and advanced manufacturing methods combine to deliver superior strength and holding power, light weight and corrosion resistance.
    • Cam profile and mult-coil spring minimise line entry and release effort.
    • Carbon fibre compoasite cam material provides maximum resistance to heat and abrasion.
    • Unique self-cleaning, self-lubricating slotted bearings ensure consistent high performance even when subjected to high static loads.
    • Carbon fibre composite cams.
    • Long strand glass fibre reinforced polymer base.
    • PTFE impregnated Acetal slotted bearing.
    • Stainless steel multi-coil spring.

    Applications:
    Range of cleats for all requirements including control lines, jib sheet and mainsheet cleating.
