    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

    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 black chromed 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.

    • Lightweight design with cheek cut outs for easy bearing maintenance.
    • Through hub mounting for maximum strength.
    • All-purpose bearing system provides maximum static load capacity.
    • Alloy upper and lower cheek plates.
    • U.V. stabilised Acetal sheaves.
    • Grade 316 stainless steel hubs.

    Applications:
    Line deflection on larger yachts (depending on load and angle of deflection), halyard and control line deflection on boats to 14 m (46 ft).
