Series 40 Orbit RT Sheave Replacement Cassette

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. 

Features:

  • Class-leading dynamic and static load ratings, highest in their class
  • 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
  • Soft attachment, lashing, and traditional swivel shackle head options
  • Low profile and compact
  • High performance cleating

Applications:

  • Mainsheet systems and spinnaker sheets on dinghies, OTB catamarans and sportsboats to 8m (26ft)
  • Halyard, vang and backstay applications on boats to 9m (30ft)
  • Control line applications on larger yachts

Clear display

I got this to replace an old iPad Pro. It does everything my old pro did, except for having a smaller screen. Good value and set up and migration from old iPad was super easy. Good battery life and so far playing games on it haven't been an issue

New Ipad
Style: Wi-Fi, Size: 256GB, Color: Yellow, Configuration: Without AppleCare+
Nice size with a nice clear picture. Replaced a very old iPad. Not all apps and things transferred like the iPhone. But very manageable with a little time. So far I am pleased with this iPad.

Its Great! Except one tiny detail

Ipad works great, easy to set up and everything transferred from the cloud from a backup I had (thank god because my other ipad is completely dead). Everything is in order except they put the magnets in the wrong spot xD. It doesnt matter functionality wise and I feel its more hassle to exchange than its worth so I am going to keep the iPad. With the case its in it doesnt really matter because theres a spot already for the pen. 4/5 stars

Excellent Screen Protector – Easy to Install and Crystal Clear
Model: iPad A16 11th 2025 /10th 2022
am very pleased with this tempered glass screen protector for my iPad. Installation was quick and easy, with no bubbles, and the fit is perfect. The screen remains crystal clear, and the touch sensitivity is exactly the same as before. It provides great protection against scratches and everyday wear while maintaining the original display quality. I also appreciate that the package includes two protectors, which offers excellent value for the price. Highly recommended for anyone looking to keep their iPad screen safe and looking brand new!”
