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

Excellent pillows that are worth the cost
Size: Queen / Standard, Color: White
These are wonderful. Completely relieved my back pain the first night I slept on them -– I put one underneath my back as I slept, and a weeklong terrible pain vanished overnight. Felt like sleeping on a cloud. As others have noted, they are neither too soft nor too firm…they’re really just right, and I think would make great guest room pillows since everyone would like them. These were definitely worth the money.

Great , fluffy pillows
Size: Queen / Standard, Color: White
They came compressed into a small roll so I was wondering how they would do. BUT they fluffed up to incredible size and comfy feel. I am impressed so far!

Pillow comfort and quality
Size: Queen / Standard, Color: White
Bought this for my husband. He is very happy with it. It is well constructed. He doesn’t like too firm or too soft. It meets those requirements. Very reasonably priced. I have bought very expensive pillows that aren’t even comfortable!

Pretty good.
Size: Queen / Standard, Color: White
Me and my fiancé have been going through a lot of pillows, trying to find the right ones. We go to this local hotel to unwind and use the whirlpool sometimes. Their pillows are immaculate. So I starting looking at “Hotel Pillows”. These are not the same as the hotel pillows, not even close tbh, but they are the best ones I’ve bought so far. They are comfy from day one. I was worried when opening the box and seeing that they had the same cover on them as others I bought before, but they were not the same. Pretty comfortable, and less neck pain than any of the other ones. My house is like the house of pillows and I am finally going to start getting rid of the old ones. Maybe we’ll find some down pillows to put on our registry, but until then, these are staying on my bed.

Pleasant surprise, warm and fluffy
Size: Queen, Color: White, Size: Queen, Color: White
For the past couple years my girlfriend and I have gone through a few cheap comforters. We never really gave much thought to them and subsequently they never impressed us. I grew up using a down comforter and have very fond memories of that blanket. The comfort and warmth was something that I hadn't experienced since I had moved out and gotten my own comforter. So this has been in the back of my mind ever since but I wasn't sure if I wanted to dish out that kind of money for a blanket and also deal with the hassle of dry cleaning it. Also by purchasing a down blanket we'd be supporting an industry in which the down feathers from geese are taken from them and that's not something we personally wanted to support. So for all those reason we started looking into down alternative. The first thing that made me question these products was the price, they seem TOO cheap. I was raised with the mantra, "you get what you pay for" and with that in mind I was quite weary when looking at these products. I always make sure to compare many different products and read through the reviews, both good and bad before I buy something. I decided to take a chance on this particular one as it seemed to be the highest rated by customers and I liked what I saw in the images provided by said customer. If anything, the price was low enough that I wasn't too worried if I didn't end up liking it. Now I wasn't actually home when it arrived but my girlfriend confirmed that it was very flat right out of the package, as was expected. By the time I got home 2-3 hours later it appeared to be fully fluffed. The material it is made of is very soft and comfortable on your skin and I was pleasantly surprised with the thickness/fluffyness. It is a fairly light blanket, similar to a down blanket I suppose in that regard. So far I have only slept with it one night but it did a great job of keeping me warm. I live in Wisconsin and the temperatures this week have been ranging from -10 over night to single digits during the day. I had been using 2 blankets prior to getting this one and sometimes I would still wake up in the night feeling cold. But so far with this blanket alone I have stayed warm which again was a pleasant surprise. I do have to say that this doesn't remind me a whole lot of my down blanket and I think that may have to do with the material used in the shell. And you're not going to be 100% able to recreate a down blanket not using down. So if you are looking for something that feels exactly like down and won't be satisfied otherwise, this might not be for you. However, if you are looking for a good quality, warm, fluffy and affordable priced blanket that will give you that "cloud" like feeling, I think you would be really happy with this blanket. Again this is my opinion from using it for one night, I can not comment on the durability or longevity of this blanket, but I am hoping that it holds up over time. **also our cats immediately fell in love with it, it is their new favorite spot to nap.
