Series 40 Orbit Single BB Single Stand-Up Block

The Series 40 ball-bearing Orbit Blocks provides the perfect balance of strength, performance, and reliability. They offer class-leading dynamic and static load ratings, the highest available in this size of performance blocks. Lightweight and strong toughened glass fiber reinforced nylon cheeks replace stainless steel straps used in traditional utility blocks - the perfect balance of performance and reliability.

As well as traditional single swivel blocks, the range includes single and double sheave lashing or soft attachment options through to multiple sheave blocks including those with quad and quin sheaves. The range is highly versatile allowing a multitude of possible systems right up to a 12:1 purchase mainsheet system for off-the-beach performance catamarans.

Series 40 Orbit Blocks are fitted with our carbon-reinforced C-Cleat for secure rope holding with low entry and exit efforts, and fairleads for fast action from any angle. Cleat arms are made from stainless steel and adjustable for setting your preferred cleating angle.

Ball Bearing versions incorporate our 2-stage bearing system using ball bearings to minimize friction and a secondary full-contact bearing to maintain low friction across the full working load range.

High Load versions are designed specifically for any application where high dynamic or static loads are expected. They feature a high-strength grade 2205 stainless steel sheave hub together with a triple bearing race to maintain low friction at very high loads.

  • Class-leading dynamic and static load ratings

Hefty but good quality!
Color: Red
It's hefty! I bought this for my 70lb Dutch Sheperd/Malinois mix because she, as the breeds are, is extremely active and loves to play tug of war. I read the reviews and knew the bone was noted to be heavy but bought it anyway. It was a little bulky for her at first and she let it lie for a couple of months but was picking it up today. I will get use out it with her as she continues to grow but definitely not for smaller dogs. It's still a good, sturdy product!

Have bought a few of these over the last handful of years
Color: Red
Best toy outside of Ghonuts for heavy chewers. Even outlasts the most durable Kongs. I'd say we get about four months before our dog starts really making a dent in it and the size of the pieces he pulls off start to become larger and I should probably replace it after about six months. It's cheap enough that replacing it that often is fine. *Important note* using squishy toys for heavy chewers is really important. They can break their teeth on hard toys like Nyla bones and things like antlers can break and cut them and damage their digestive system if they swallow the shards. It sucks because my dog loved Nyla bones and would chew off an inch a day, but I couldn't risk his teeth like that.

Finally - a tug toy my dog hasn’t destroyed!
Color: Red
This completely exceeded my expectations! My dog is roughly a year old, about 110-115lbs and a TOUGH chewer. He loved tugs toys but none of them last more than 10 minutes with him. I decided to try this because of the other reviews and price but wasn’t expecting it to last long. He’s had it almost a week and it’s still completely intact. It’s definitely heavy so it might not be best for smaller dogs but if you have a big dog/heavy chewer definitely give this a shot!

Indestructible so far
Color: Red, Color: Red
My toy destroyer has had this for almost two months now and it hasn’t taken any damage. It is big and heavy and solid. It became one of his favorites immediately and goes in and out of the house and even to bed with him. Now if only we could find a stuffy that he can’t destroy.
