Series 40 Orbit BB Quad Block with 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

excellent
Color: 1PC Amber White 6 Modes Lights + Wiring, Size: 12Inch Light Bar
The light is impressive with six modes. The wiring harness was already prewired relay and a protective cover over the wiring. One problem was the sizeable in-line connector for the switch made it difficult to place it inside the vehicle due to the length of the wire. Negative--The mode switch will not work unless the power is on and no indication of which mode it is currently in.

I installed this light at on my 25hp New Holland Tractor for some light assistance with plowing snow. Very easy to install and provided a ton of light that was needed. Wish I had a photo to share.
