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.

  • Lightweight
  • Highest working load in its class

Great Chew & Flavor
Size: 1 Count (Pack of 6)
My dogs chow down on these great crunchy/crispy snacks. Great for light to medium chewers. My intense chewer loves the flavor...but he can get through one ear in less than 20 minutes (on a relaxed day).

My dog loves these pigs ears, she's a 20 lb Shih Tzu Jack Russell mix, I cut the ears in half but they're still going within 10 minutes.

I have always thought these were great but this time they were black. Didn't look fresh. Don't know if I will buy again.

Just right for a small dog
Pattern Name: Half Ears, Size: 25 Count (Pack of 1)
Perfect for my 9 lb mini schnauzer. It's her #1 favorite treat. Keeps her busy for a long time (a few hours). Great quality. Bag lasts a long time. Have purchased multiple times.

Great product and value for the money
Pattern Name: Half Ears, Size: 4 Pound (Pack of 1)
Dog loves these. I only feed her natural food and treats. These are very healthy. She's a strong healthy 2 year old puppy. Will be buying again soon. It is a great product for the money. They are chewed up in minutes because she loves them. They do have a bit of an odor but it's not overbearing.
