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
  • Low friction 2-stage ball bearing system for efficient and effortless trimming

No worth buying
Size: 24+19
Not worth buying, 1 month after installation they stopped working well you could see the rubber piece that makes contact with windshield was loose on the verge of coming off, it was put on our 22 civic one that isnt used very often, so the fact that they died out so easily was disapointing, i plan on looking for some better ones and avoiding this brand 👎

These are fantastic. They were inexpensive, which made me nervous, but they are definitely high quality. They were all 3 super easy to install. Highly recommend! They also don't leave my windows streaky.

Genuine Lexus Filter / Quick Delivery
Initially I had installed non-genuine Lexus filter, which the seller claims it fits Lexus RX. That filter fits (kinda). After installing the air-filter and closing the lid, I could see the edge of the filter because the lid did not close tightly. I am not a mechanic, but I was concerned. Hence, I ordered the genuine Lexus filter from Lexus dealer through Amazon. I paid twice more than non-genuine filter (including extra shipping charge of $10.00). Genuine filter arrived in the FEDEX box (looks and feels pretty sturdy enough to protect the filter) only 2 days after I placed the order. I have just replaced the filter. The lid closes perfectly. Although I spent total $40, for the peace of my mind, it's the money well spent.
