Series 40 Orbit BB Quin 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.

  • 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

ring is as good as pictured. gorgeous!
Gem Type: No Gemstone, Ring Size: 10
This ring is beautiful and sized perfect. However, on the second day, one end of the little curly-cues came loose and is sticking out. I need to sent this back to be repaired. I hope this will not prove to be too difficult!

These are a good choice
Color: Black-2 Set
These are great. They are made well, look nice and are easy to move when I’m dusting. I use these to keep perfumes, lotions and vitamins organized atop my dresser. The velvety compartments are a well sized and the layout is conducive to storing the kind of objects women or men typically store atop a dresser. I find these bins quite functional. I feel like these were a good value. They weren’t the cheapest and they weren’t the most expensive. They look nice and feel high quality enough.

Nice and works great in my nightstand
Color: Beige
Smaller than I expected, but good quality and looks nice in my nightstand drawer. It will keep things from rolling around. Seems sturdy and I like the pinkish undertone to the beige.

Great end table organizer, Style, size, cost
Color: Brown-2 Set
Good size, very useful tray. The large compartments are laid out well. Small areas good to hold a watch, change, lip balm, etc. Affordable price and made well, looks more expensive. Keeps "stuff" neat and clean.
