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

Among the best!
The only automatic wine opener I found with five stars. Used it daily since purchased and agree (thus far) it has earned every one of them. I have several bottles with stubborn corks that challenge every manual opener I've had. This tool handles them with ease. Especially neat is the way it "spits out" the cork after extraction. Very attractively and well packaged. Add a little gift paper and you're set. (Daily use since purchased and not even close to needing to be charged).

Nice features
I have only had this item a few weeks. But I like it very much. It’s better than the one it replaced. I like that I only have to press and release the button to pull out the cork and then it releases the cork automatically. Only charged once so far and is still fully charged. Also a blue LED is lit when cork is being removed and a red LED is lit when it is releasing the cork.

Don't Waste Your Money!
I thought this was going to be good. First bottle opened OK, though the device obviously struggled to get the cork out. Used for 3 or 4 bottles. on the last two, I had to manually turn the device to get the corkscrew in - then pull the cork out. Cork is in the device and it won't come out. UNFORTUNATELY I THREW OUT THE PACKAGING, SO NOT SURE WHAT IF ANYTHING I CAN DO WITH IT OTHER THAN THROW IT OUT. NOTE: I did try recharging the device after each use, though it made no difference.

Works great! Better than a Rabbit brand
This is an awesome opener. My husband originally got me one for Christmas for our lake place. Everyone that uses it loves it. I had a r Rabbit brand at home and it finally wore out, but never worked as awesome as this one. My old one also required it to sit in a plastic base as a means of charging versus a cord I can simply plug in and hide. I like this style better because I can put it on a cute little tray. To work it, you simply push a button and it pull the cork out and then releases it without having to hit a different button. This one was on sale too, so extra bonus.
