Series 40 Orbit BB Triple Block with Swivel Shackle

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.

Features:

  • Class-leading dynamic and static load ratings
  • Lightweight, yet strong. Toughened, glass fiber reinforced nylon replaces stainless steel straps used in our traditional utility blocks
  • Low friction 2-stage ball bearing system for efficient and effortless trimming
  • Soft attachment, lashing and traditional swivel shackle head options

Stylish and practical backpack for work and travel
Color: Upgrade-apricot, Size: 15.6 Inch, Color: Upgrade-apricot, Size: 15.6 Inch
For both everyday work and travel, this bag has proven to be an excellent option. I can feel secure bringing my computer around because to the 15.6-inch laptop compartment's solid fit and ample padding. Notebooks, chargers, and a few personal belongings can fit in the spacious main compartment without feeling crowded. The apricot color looks polished but still casual enough to wear outside of work, and I really enjoy the sleek and fashionable shape. Even when the bag is completely packed, the straps remain comfy, and the stitching seems sturdy. I particularly enjoy that there are several pockets, including smaller ones for a phone, pencils, or keys. It makes everything accessible and well-organized. If the material gets a bit dusty while traveling, it washes clean and the zippers open smoothly. It is lightweight, adaptable, and functions well as a carry-on, purse-style bag, or business backpack. All things considered, it's a good everyday bag that is both practical and stylish.

Perfect for a backpack or a purse
Color: Upgrade-black, Size: 14 Inch, Color: Upgrade-black, Size: 14 Inch
I love this black backpack. It has gold zippers and brown accents and it has a pocket in the front two on the side three inside and a pocket on the back of the laptop pocket. I have a disability and have to carry extra stuff so this is a perfect size for me to wear in my back every day. It’s black nylon so it should stay clean. I tend to drop things. I think this will be great, but even without a disability, this is a great backpack. It’s so cute.

Perfect day bag!
Color: Upgrade-black, Size: 15.6 Inch
Super convenient and lightweight. I used it for two back-to-back conferences last week and it was PERFECT for what I needed to tote along all day. Fits my regular sized computer (15-16 inch) and even held my water bottle (which is larger than a regular plastic water bottle).
