    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

    Swivel cleat bases permit easy cleating and releasing from any angle.Height adjustable arm for optimum cleating angle. Twin ball bearing race minimises friction. Adjustable ratchet system prevents the arm from falling to leeward. Twin rows of ball bearings support the cleat arm, and stops are provided to limit rotation to 260° and can be removed to allow full 360° rotation. Fork fittings have a 5 mm pin to permit direct attachment to the head post of a block (ie. not using a shackle). Suits traditional post/shackle head blocks and Dyneema® Link head Orbit Blocks™.

    • Height adjustable arm.
    • Twin ball bearing race.
    • Adjustable ratchet system.
