Series 40 Orbit BB Quad 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

finally organized all my jewerly!
Color: Black
This jewelry box completely transformed the way I store and access my accessories. It’s not just functional, it’s genuinely beautiful, with a sleek design that looks great on my dresser. The exterior feels sturdy and well-made, and the interior is soft and luxurious, keeping all my pieces protected and tangle-free. There’s a perfect place for everything: rings, earrings, necklaces, and even watches or bracelets. I especially love the multiple compartments and drawers, which make it easy to separate everyday items from special pieces. No more digging around or untangling chains! The mirror inside is a thoughtful touch, and the box itself feels compact enough for smaller spaces while still holding a surprising amount. It’s one of those things that makes daily routines feel a little more put-together. If you’re looking for a jewelry box that’s practical, elegant, and gift-worthy, this one checks every box. Great for personal use or as a thoughtful present.

Prefect Travel Case
Color: Black, Color: Black
I got this for taking my jewelry on the go. I have to say that I was pleasantly surprised by the quality it feels very sturdy. It has several spots to hold jewelry and keep it organized. The outside is textured and it closes with a snap which can be done easily.

Small, bu holds a lot
Color: Black
I initially purchased the Jewelry Box Necklace Ring Storage Organizer as a gift for my 8-year-old daughter. The compact design and practical features seemed perfect for her little trinkets. However, its quality and style so took me upon receiving it, I decided to keep it for myself! The jewelry box is small, but it holds a lot with a double-layer structure that provides ample storage space for various types of jewelry. It easily accommodates rings, necklaces, and other small accessories without clutter. One of the highlights of this product is its portability. Its compact size makes it an ideal travel companion. I've taken it on several trips, and it has proven incredibly convenient. It keeps all my jewelry neatly organized and easy to find, eliminating the hassle of untangling necklaces or searching for a matching earring.
