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 optimization and the cut-away design minimizes 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, minimizing 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.
Ideal for creating simple vang and mainsheet systems up to 4:1 on boats to 12m (40ft)

It’s a Nice Big Bag!
Color: Blue Flowers
I bought this bag for my mom as a Christmas present and she loves it. She’s a big purse lady, so it is the right size for her. It has all the pockets in the right places and she loves the pretty floral design.

Love the style and Multi pockets!
Being a traveling float Phlebotomist for a very large company I need a bag that is extremely well-made holding my schedules.. my books, my PPE outfit, and all other essentials I need for my position. This bag is definitely the one very well-made, multi pockets more than enough room for everything that I need to carry all my equipment for me… to each job. Definitely would recommend this to anybody who travels in their job. Definitely purchased from this company again. Shipping was very fast and the product is in my eyes perfect.!

Beautiful, sturdy and comfortable!
I am very satisfied with this bag! I honestly thought that because the price was so low that it would be more of a lightweight beach bag, however, it is very sturdy and holds so many things. The straps are very thick and comfortable. There are a few pockets inside zippered pockets of some side pockets and a front zipper pocket. I get so many compliments on this bag. Two of my friends actually bought the same bag! I honestly want to buy another one just in case somewhere down the road something ever happens to this one because I am obsessed with it. I use it every day for work is very easy to clean as well. It’s almost like a neoprene type of fabric so it wipes off very easily. I highly recommend this product.
