FEATURES & INFORMATION Keeoat Blocks SERIES 100 Use Them Anywhere A balanced design approach incorporating functionality, performance and style makes our Series 100 Core Blocks the right choice for performance cruising or racing applications. A full contact bearing 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. Glass fibre reinforced nylon sheave, alloy cheeks and stainless fixings complete the durable package. Dynamic and high static load performance Core Blocks incorporate a full contact acetal bearing on a polished stainless steel race to maintain low friction performance under heavy loads. 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 foot blocks. Fully articulated standup Standup models have a linkage that provides full rotation and articulation. A high strength precision cast padeye minimises the footprint and a dedicated rubber boot ensures the block is held upright when not loaded. Universal head The head assembly incorporates a brass bearing washer to provide smooth 60 rotation of the post and shackle. A set screw arrangement allows the head to be locked at 0 or 0. Shackles are high quality forged grade 174PH stainless steel. Aluminium alloy cheek plates Block cheeks are manufactured from the highest quality aluminium alloy for maximum strength, and hard anodised for durability and corrosion resistance. Material optimisation and the cutaway design minimises weight and allows easy fresh water rinsing of salt and debris from the bearings. The hollow hub can be used as a becket takeoff or tieup point. Suit prespliced lines Removable becket pins allow fitting of prespliced lines. The flush fit becket pin head is kind on deck surfaces and won t snag lines. Also available in Series 4, 60 & 7.
