Series 30 Ball Bearing Block Single Becket Option Lashing

Ball Bearing Blocks™ boast the highest strength-to-weight ratio available.  This is achieved through all-composite reinforced polymer materials and multiple attachment options. Their precision design provides the optimum number of ball bearings for minimum friction while weight reduction is achieved through the use of fibre-reinforced composites in the block head, cleat arms and beckets. 

Highest Working Load in its Class

The proven Ronstan 2-stage bearing system (Series 30 and larger) features high compression grade Acetal ball bearings and a secondary full-contact bearing. This gives minimum friction across the full working load range.

The sheave and bearing system is supported by a fibre-reinforced load frame, computer modelled and optimised using advanced stress analysis methods. The Dyneema® Link, used in multi-sheave blocks, is produced from high spec SK75 fibre, which is 10 times stronger and lighter than steel, and provides the final connection from the block to the load point.

Simple, Versatile & Secure Attachment

The single block is easily lashed to an attachment point, and can also accept Dyneema® Links and shackles for a variety of efficient attachment alternatives. The Dyneema® Link used in multi-sheave blocks is easily fitted and secured by a removable pin. The Dyneema® Link can also be removed and replaced by a shackle, custom lashing or strop.

These blocks are far more compatible with Dyneema®/Spectra® lines, carbon laminate connection points and webbing than traditional blocks with steel loop tops or shackles.

Low Profile & Compact

The two way head in the single lashing block allows for alignment at 0° or 90° orientation, while the single swivel block allows for full articulation.

The flexible Dyneema® Link used in multi-sheave blocks provides 0° or 90° orientation. It connects directly to the head of the block rather than to an intermediate head post. This reduces weight and gives the lowest possible profile while allowing full articulation. Beckets have been carefully designed to minimise height.

Features:

  • Lightweight
  • Highest working load in its class
  • Secure, versatile and secure attachement
  • Low profile and compact
  • Ultra low profile thru-sheave becket
  • Self-lubricating Nylatron® sheave and full contact bearing for high dynamic loads

Applications:

  • Halyard, vang and backstay applications on boats to 5M(16')
  • Control line applications on larger yachts

Great!
Color: 2-Pack White, Color: 2-Pack White
I wish I’d have taken a before photo. But imagine a bunch of spices, on a little spice shelf that makes a U formation and a bunch of spices in the middle. So many spices. So much maneuvering to find the right one. This- this is great! Organized, easy to see, reach. Neat. Excellent investment. It doesn’t even look like I have a lot in there, but I have 46 spices in there! And you’ll notice my cabinet has a lip. Easily fixed with a small piece of wood to raise the item.

Well thought out and easy to install
Color: 2-Pack Black, Color: 2-Pack Black
Definitely organizes and maximizes cabinet space for spice storage. It’s a little rickety. If you are using glass spice jars you will likely need to use the included screws into the cabinet because the double face tape it comes with might not hold up. It might work with the plastic spice containers, but even then it seems like it would not be sturdy enough to hold the weight. The instructions were clear and it installed quickly. If it lasts, it was definitely a value upgrade in my cabinet.

Don't buy the other brands
Color: 2-Pack Black
I'd give these a 10 if I could. I bought another version but returned ii because I didn't think it was very sturdy. These were only $8 more and what a difference. They are a very well made and a lot more sturdy. The extra $8 was a real bargain and well worth it.

Great for short people to see and retrieve spices from upper shelf! Holds a lot of weight easily!
Color: 2-Pack Black
These spice racks were very easy to install in my cabinets. Actually, I have only used the adhesive, and they are holding all of the weight of the spices without any issue! These are remarkably heavy duty. I am short (5"3") and most of the second shelf is not really very useable without a stool. I can pull these out and turn the racks making all of them visible and easy to reach! I have two and I'm seriously considering ordering more! It makes organizing a breeze too!
