Ball Bearing Orbit 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.

Note: When using these accessories as a mounting option the breaking load is reduced to 1300kgs (2860lbs).

Lightweight

Kilogram for kilogram of working load BB Orbit Blocks™ are the world’s lightest. To gain peak performance, we engineered out the heavy steel load straps, head post, shackle and cleating accessories. Through extensive research and development, we replaced virtually all metal components with high-tech polymers and fibre equivalents.
Weight and bulk are further reduced in the different block configurations. The ball bearing single and becket block has a through-sheave becket arrangement. The result? - The lowest weight possible.
Multi-sheave blocks have only single intermediate cheeks and an ultra-light and efficient head arrangement. Other brands just link together their single blocks with a heavy steel channel across the top of the block, with unnecessary extra cheeks adding extra weight and bulk not found in Ronstan Orbit Blocks™.

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.

Phoebe approved! 3 months and still going!!
Color: Hammer, Size: Large, Color: Hammer, Size: Large
I have 2 dogs--a chocolate lab and a pittie mix. Normally, they shred their toys within minutes/hours if not days, but this one has lasted for over 3 months! It is well loved and starting to show some wear, but I am super impressed with how long this one has lasted. It has a couple holes in it but they haven't disemboweled it. The squeeker didn't last too long, but they never do.

Good for modest chewers who don't destroy toys.
Color: Hammer, Size: Large
We have four dogs, one of whom is a super chewer. Unfortunately, this toy wasn't even durable enough to stand up to our mid-level chewer. She had the squeaker out of this in mere moments, and the rope was untied and in shreds. We had to basically remove the squeaker from her, then clip the rope from the toy so she didn't try to eat it. Now, don't get me wrong. She's still having a great time with this toy, even as she whips it around and tosses stuffing everywhere. This is definitely sized for medium to large dogs, but I would only recommend this to dogs who don't like to destroy their toys, but instead just like to squeak them and maybe play some light tug. For those dogs, this will be a great option. For super chewers, this will last only minutes and I would not recommend it.

Fun Toy for Fun Times
Color: Hammer, Size: Large
Perfect fun toy for my dog! I bought this squeaky plush toy for my dog and it has been a huge hit! The design is adorable — like a little toolbox toy — and the material feels soft yet durable enough to handle lots of chewing. The squeaker sound gets my dog’s attention every time and keeps him entertained for ages. It’s a great size for playtime and fetch, and so far it’s holding up really well against rough play. Highly recommend this if you’re looking for a fun and engaging toy for your furry friend! She chews it up and has a good time. Good price.

Very durable for a plush toy
Color: Hammer, Size: Large
My GSD husky mix loves this toy. She is "working on it" as I write. Her first call to action with any new toy is to get the squeaker out. This toy is well made enough so that she has not been able to reverse engineer it immediately (as she does with cheap dog toys). She seems to enjoy chewing on the handle making it squeak, which is pretty cute. The toy itself is bigger than I thought it would be which is nice, as my dog is bigger too. It is soft and well stuffed. The rope on the end will make it a great tug toy too. Right now it has my dog's full attention so we shall see how long it lasts. Overall, while not indestructible, it's definitely better than 90% of the toys we've gotten her so far in terms of durability. Great product!

Seems sturdy so far
Color: Screwdriver, Size: Large
So far my boys haven't ripped this apart, which is a good sign. They like to play tug with it and the squeaker is engaging (my pittie loves squeakers). Here's hoping it continues to last with my 2 tough chewers.
