Product Description
Ronstan Series 100 Single Orbit Block
Product Information
Orbit blocks™ are a no-compromise product range developed to meet the demands and expectation of the very dedicated and increasingly professional racing sailor. Side cheeks incorporating head structure and hub are precision machined as a single part from solid alloy, leaving material only where it contributes to the load carrying capacity of the block and eliminating the need for additional fasteners. The Orbit sheave has captive Acetal or Torlon® ball bearings for side thrust loads, eliminating the need for side retainer plates. This reduces weight and allows for a wider bearing surface that can accommodate longer Torlon® needles – achieving a substantially higher strength-to-weight ratio.Head posts of swivel blocks can be locked at 0 or 90 degrees.

FUN TOY!
Got this a couple days ago and so far very pleased. Would give it 5 stars, but only had it a couple days - we will see how it holds up o er time. All 4 of my dogs love it, so much so that I ordered more today. It's got an awesome squeaker, and is flexible without being flimsy. My guys haven't destroyed it yet, and that's always a good sign.

Good quality, great for the beach
This is great for ocean and beach fetch! The spikes keep the sand and saltwater from getting in my pups mouth and upsetting her stomach. It also floats well and doesnt fill with water. I have had this for about a month now and in surprisingly good shape considering how obsessed with it my dog is. Not gonna lie, I avoid squeakers since my dog is an absolute menace with them but i assumed the squeaker would break almost immediately, however it is still going strong much to my annoyance🤣

The dogs like it very much, it produces a lot of noise.
Size: Large, Size: Large
I’m rating this based on my dogs’ response to this toy – they absolutely love it, and it has seen more use without damage than any of their regular throwing toys. At the same time, unless you enjoy, REALLY ENJOY the sound of crunching water bottles, you may not like having this ball in the house.
Pros:
The rubber outer shell of the ball is durable, and can survive both chewing and pulling forces (as a note, my dogs do not concentrate on chewing - they use it more for play games). It’s big enough for my dogs to play tug of war with it, hooking their teeth in the mesh, and they since it bounces around if they drop or kick it, it makes the game more interesting than rope. They did crush the interior plastic, but they don't really seem to care.
It’s much more engaging than a normal ball, and can be modified to hold treats, sticks, rope elements and other external bits, which my shepherd mix loves; he gets bored easily and frequently, and this can actually entertain him.
Cons:
This toy is loud, and produces repetitive crunching sounds. It is apparently really engaging to chew, and my dogs will produce the horrid plastic crackling up to half an hour at a time. If you let your dogs in and out, it would make a fine outdoor toy, but since I have a dog door, it migrates around to pretty much wherever the dogs are. I kind of hate it, but will probably buy another if they break this one since they enjoy it so much.
