Series 60 Core Block - Single - Becket

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.

Universal head
The head assembly incorporates a brass bearing washer to provide smooth 360 rotation of the post and shackle. A set screw arrangement allows the head to be locked at 0 or 90.

Shackles are high quality forged grade 316 stainless steel.

The Power of Story in the Information Age
Format: Hardcover
After reading John Inazu's first book 'Confident Pluralism', I thought this might be a deeper foray into the legal/cultural difficulty of living faithfully in a pluralistic society. Instead, Inazu and Keller do something different. They challenge us to listen to stories of folks seeking to embody the principles of 'confident pluralism'. Does it offer easy answers? No. However, it does offer us a window into the rich ways that God can move us, transform us and position us for His purposes in communities where we might have deep disagreements. Overall, these stories of small and large acts of faithfulness to exemplify Christ's humility, patience and tolerance were deeply encouraging to person that constantly tries the patient of a God whose love he does not deserve. Very thankful to Inazu and Keller for organizing this. This is an important conversation in an acrimonious age where we falsely substitute information/vital statistics for people/real relationship.

easily accessible stories for engaging the culture
Format: Kindle
Inazu gathers stories of Christians seeking to engage the broader culture while maintaining their faithful beliefs. I appreciate the varied perspectives, though not agreeing with all, but then his four categories as the beginning of practicing this. That one line demonstrated a humility that I appreciated. This brings practical application into a narrative form that should be easily accessible

A Breath of Fresh Air
Format: Hardcover
In a world that is filled with Christian books on how to defeat culture or to escape from it this book is a breath of fresh air. In the 10 years that I have worked with young people one of the hardest concepts to get across to them is that their work matters. And even beyond that, how do we work with or partner with people who are different than me? How do we work together for a common good? That they have opportunities to engage the world around them. This book helps to give words to what that looks like. Not only is it filled with diverse writers, it doesn't give easy answers but ones of hope. I am grateful for this work and will share it with any college senior, young adult, and parishioner that I can. BUY THIS BOOK!
