Series 40 Orbit BB Triple Block with Becket & 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

Durable & protects well
I’ve had this case for a few months and it is holding up great. It is bright and easy to distinguish from other tablets & devices in our home. My iPad 2025 snaps securely in place. I have dropped my iPad many times and this case has protected it every time. I love the rotating feature of this case as well. I highly recommend this brand in whatever color you decide

Sturdy
The case is pretty substantial. The color is nice and I love that you can swivel my IPad for viewing. The only thing that I would change would be to have the pencil holder be removable or let it fold back if you don’t need it.

Great case for the money
Color: Tea Brown
Love the case. Installation was an easy Perfect fit. The leather seems to be fairly scratch resistant. which was important for me working construction. I do not have an Apple Pencil so I can not speak on that portion of the case. The keyboard back light changes colors, I prefer to keep it on a softer setting. It doesn't take long to charge, and connects via bluetooth seamlessly . The magnet could be a little stronger, but it does work fine.
