Series 40 Orbit RT Triple Block with Becket, Cleat & Swivel

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 also 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 extremely 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

Nice
Number of Items: 5, Color: Navy/Charcoal/Cardinal Red, Size: Large
My husband really likes the quality of these t-shirts. They fit nicely and dont have a sagging neckline as some t-shirts tend to have. The colors are nice and they wash up well. Not a heavy so comfortable for everyday use whether relaxing, doing yard work etc

Great t shirts
Number of Items: 5, Color: Navy/Heather Navy/Indigo Blue, Size: Large
Great t shirts. They fit great, and are very comfy as an under shirt or just a solid color shirt. Have washed them multiple times and they still hold up good, don’t wrinkle easy, and colors have stayed nice. The fit is great, can definitely be used for work, gym, whatever, just good comfy shirts

Bought in multiple colors! Fantastic material
Size: X-Large, Color: Light Green, Size: X-Large, Color: Light Green
I ordered this button-up for an upcoming beach vacation, and I’m honestly so impressed with the quality and feel of it. Right out of the package, the material felt soft, breathable, and exactly what you want when you know you’ll be spending long hours in the sun and heat. It’s incredibly lightweight without feeling cheap or flimsy, which was one of my biggest concerns when ordering. What I really love is how well it helps keep you cool. The fabric allows for great airflow, so you don’t feel like you’re overheating or sweating through it like you might with heavier shirts. Even just trying it on, I could tell it’s going to be perfect for hot, humid weather. The fit is also spot-on—not too tight, not too baggy—giving it a clean, relaxed look that works great for both casual outings and slightly nicer dinners by the beach. Overall, this shirt checks all the boxes: comfortable, breathable, stylish, and ideal for vacation wear. Already grabbing a few more colors
