Series 40 Orbit Single BB Single Stand-Up Block

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
  • Soft attachment, lashing, and traditional swivel shackle head options

Great spice rack
Style: Three 2"W Drawers, 2-Tier
Love this rack. It was easy to install and is very sturdy. The shelves slide very nicely on ball bearings making it easy to read spice labels

Good for organizing
Style: Three 2"W Drawers, 2-Tier
These work well. Check the size of the lip on your cabinets if installed on bottom shelf. The screws were way too long and they were not the same between both sets of racks. A trip to the hardware store will be needed.

Good purchase
Color: Gold, Color: Gold
It matches my decor and it was easy to assemble. I have been using it for the past month and so far it has done what’s it’s supposed to do, look pretty and hold the tissue roll in place. I am sure it will last years.
