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

GET IT! Luxurious, soft and modern
Color: Black, Size: King (108" x 90"), Color: Black, Size: King (108" x 90")
I don’t write many reviews, but had to for this one. This blanket is SO SOFT and it has a little weight to it. The king size is perfect and even a little longer than most king comforters. It is double sided, so the underside fuzz is a little shorter. It kept us warm but not too warm. If you overheat easily, this is perfect. I didn’t notice any shedding. I haven’t washed it yet but hopefully it won’t lose its luster once I do. I love the bubble pattern of the fur. The fur is luxurious and not cheap looking. It looks amazing on our bed.

Amazingly soft and beautifully made!
Color: Cream White, Size: Twin (60" x 80")
I was on the fence about purchasing this blanket as I was looking at other options and having trouble deciding. I ended up taking a chance on this one and I'm very happy with the result. This blanket is exceptionally soft and will keep you toasty warm. I keep mine at the end of my bed. It adds a cozy aesthetic to my bedroom. To put it simply, this blanket is both functional and beautiful. Mine arrived in a air-sealed bag, but it fluffed right up the moment I opened the bag. I decided to wash mine before using it, however, it did not have any unpleasant smell that made me do so. My only reason for washing it is because I have allergies and sensitive skin, and it was more a precaution than anything else. Regardless, it washed up nicely and even after coming straight out of the washer was still fluffy and soft. If you also decide to wash your blanket, DO NOT put it in the dryer. You will absolutely ruin the faux fur if you do. I hung mine up on the staircase banister to dry overnight and it was ready to toss on my bed the next morning. What I'm super impressed about with this blanket is that I haven't experienced any shedding whatsoever. I haven't found fur on my bed, there was no fur in the washer, nor have I found any tufts of fur after dragging it back and forth from my bedroom to the living room. It's a quality blanket that looks exactly like the more expensive name brand ones, but without the hefty price tag. I'd also like to note that my cat LOVES laying on it. I'm going to order a smaller one specifically for him to put in the living room on his bed.

A blanket lovers dream!
Color: Linen, Size: Throw (50" x 60")
Absolutely obsessed with these! I've literally bought 7 of them, in various colors and sizes and they are all gorgeous and luxurious! I won one of the name brand blankets like this at my work Christmas party. You know the one, $300 for the oversized (twin size) throw… when I got home and looked it up to see the price because I had never heard it it, I guess that triggered the “similar item” recommendation, and I saw this blanket. While I DO love the $300 one, I would never spend that much on a blanket. I was curious to see how this compared, for literally a tenth of the price, so I ordered a few as gifts. I figured if nothing else, my dog would love them. Now, I will say that the name brand one has the faux fur on both sides and is a little softer, but this is a GREAT quality dupe. This one even has the “heavy” feel to it like the name brand. I ended up ordering several as gifts and then a couple of the throw size for me. This is a great gift for someone, or just to jazz up your bed or sofa!

The best!!
Color: Black, Size: King (108" x 90")
I love this blanket so much. It is super soft and super warm and super cozy. I bought a couple extra and absolutely love it. The quality is really nice. I haven't washed it yet so I don't know what it's gonna be like once I wash it I would assume hang dry and not put in the dryer and wash on delicate other than that's it's nice
