Product Information
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 10m (33ft).
Various control line applications on larger yachts.
Alloy sheave models are available for use with wire.
Materials
Sheave: U.V. stabilized Acetal

Fantastic and memorable Advent companion book & cookbook
Format: Hardcover
I love this book so much! (I've now bought 3 more copies for friends and family. It's that good!) It has bite-sized little readings for each of the four weeks of Advent, then it has a bunch more content for Christmastide. It has beautiful, hand-drawn recipe pictures and quote illustrations throughout along with many excellent recipes, Advent reading lists, music recommendations, and craft ideas. I'm not a crafty person, but it did help me with ideas for decorating my Advent wreath. Additionally, I've made multiple recipes from it, and we loved them all! The baked eggs and sweet/spicy bacon and gingersnaps are fantastic. I have more recipes planned in the weeks to come. The ideas of a Christmas simmer pot for using up older fruit and cinnamon sticks is great! What I love most is the festive yet accessible and contemplative, friendly nature of the author's writings. This is a lovely gift for yourself or for others. You won't want to do ALL of the ideas in any one year, but you'll return to it year after year for new ideas and for the ones you loved from last year!

Lovely Book!
Format: Hardcover
Written as a companion to Advent and Christmastide, I could not wait until then to start reading this book. Lanier Ivester's writing is compelling and thought-provoking. Jennifer Trafton's art throughout the book is rich and beautiful. The writing and art accompanied by recipes, menus, devotional suggestions, music recommendations, and craft ideas make this a book I will be pulling out year after year. "Look now, for glad and golden hours come swiftly on the wing. O rest beside the weary road and hear the angels sing."
