Product Information
The new Series 40 ball bearing Orbit Blocks™ provide the perfect balance of strength, performance, and reliability. They offer class-leading dynamic and static load ratings, the highest available in this size of performance blocks. Lightweight and strong toughened glass fibre reinforced nylon cheeks replace stainless steel straps used in traditional utility blocks - the perfect balance of performance and reliability.
As well as traditional single swivel blocks, the range also includes single and double sheave lashing or soft attachment options through to multiple sheave blocks including those with quad and quin sheaves. The range is extremely versatile allowing a multitude of possible systems right up to a 12:1 purchase mainsheet system for off-the- beach performance catamarans.
Series 40 Orbit Blocks™ are fitted with our carbon reinforced C-Cleat™ for secure rope holding with low entry and exit efforts, and fairleads for fast action from any angle. Cleat arms are made from stainless steel and are adjustable for setting to your preferred cleating angle.
Ball Bearing versions incorporate our 2-stage bearing system using ball bearings to minimize friction and a secondary full-contact bearing to maintain low friction across the full working load range.
High Load versions are designed specifically for any application where high dynamic or static loads are expected. They feature a high strength grade 2205 stainless steel sheave & hub together with a triple bearing race to maintain low friction at very high loads.

This a an excellent comprehensive text that would be an asset to any project manager.
Format: Kindle
This is the best project management book I have read in many years. It is structured in a comprehensive and clear format that allows the reader to follow the author. The author has also provided clarity on different methods of project management that can be used to manage a variety of projects with examples of how each method can be applied. In addition to the knowledge of project management and excellent examples of how each method can be applied the author has provided keynotes to other references a reader can seek out for additional reading. This is an excellent text that I wish had been available to me years ago. 👍🏻

Become a Project Management Pro
Format: Kindle
This book is all about the ins and outs of managing a project from start to finish, and it's broken down so it's easy to understand. The practical examples helped me understand the concepts, and I've been using the tips at work, making my projects run smoother than ever. I especially appreciated the step-by-step guide to implementing these principles.
If you're new to project management, or if you've been winging it and want to step up your game, I'd highly recommend this book.

Easy to use organized guide that takes you step by step through a process
Format: Paperback, Format: Paperback
I've been investing in real estate for 5+ years and have worked for a private equity group as Director of Acquisitions. To be successful as an investor, you need to have a system. That's what I like about Symon's book. He presents a very systematic way to invest in real estate.
The Table of Content presents a strong outline that takes you from the Why of real estate investing to How to expand your portfolio and work with partners.
The book also has several helpful charts and images to drive home each lesson.
Although the book feels comprehensive like a textbook, it's written in a way that's easy to understand and logical to follow.
Symon's approach is also very metrics based (see photos). His scorecards help you test out your ideas by creating objective metrics to look at.
I highly recommend this book!
