Product Information
The new Series 40 ball bearing Orbit Blocks™ provide 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 fibre 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 also 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 extremely 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 are adjustable for setting to 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.

My granddog loved these, they were a little gift for Christmas, okay for a one off but too expensive for the amount you receive.

He loves them! Eats the entire strip!
Pattern Name: Strip, Size: 3 Ounce (Pack of 1)
Our puppy is the pickiest eater ever ! But he loves these chewes , Kingsley is a tiny Morky that will turn up his nose at just about everything . But one day I saw the chicken chews on Amazon, and thought let’s try . To our surprise , HE LOVES them , and actually looks for them in his treat Jar. They are easy for his little teeth to chew on , and he can carry them to his hiding place, for when he wants a good chew.. the great thing about them is that there is no longer any uneaten bits of raw hide chews all over the floor to step on . He eats the entire chicken strip, and I no longer have to worry about him chocking on tough leather chew strips that smell, and get slimy

Chihuahua puppy loves these!
Pattern Name: Strip, Size: 3 Ounce (Pack of 1)
My little 13-week-old, 2.4-lb Chihuahua pup loves these chews. They are the perfect size for her tiny mouth.
I hold them for her, and when enough gets chewed that it could break off and possibly cause a choking hazard, I cut that soft part off with the scissors.
-I would never give them to her unsupervised.
-Will purchase again.
