Series 40 Orbit BB Double 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

Suction cups aren’t the best
Color: Black+Smiley Face
The suction cups don’t hold and my smiley sponge isn’t snug on the post so it sometimes falls off.

Sticks and stays in place!!
Color: Black+Smiley Face
Love love loveeee this! Took me a while to find one that actually sticks and stays in place. I've had mine for a few months now. Looks just like the photos & comes with the suction cups and an adhesive strip if you want a firmer hold. The suction cups work just fine. Would recommend 👍🏾😁

Very easy to put up and assemble!
Size: 48 inch 3 Tier, Size: 48 inch 3 Tier
We were looking for a nice shelf over our coffee bar, and this industrial pipe shelf was perfect! This was very easy to assemble! Simply put in your anchors and screw in the bases! We ordered the three tier shelf but only needed two, and it was very easy to make that adjustment! I loved that this was solid wood shelving rather than particle board.
