Series 40 Orbit BB Quad 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

Dress look, without paying, big dollars!
Size: XX-Large, Color: Khaki
Well worth the $. With a sweater, perfectly fine for winter wear. Without a sweater? Perfect for fall Nice look You’ll need to have it ironed, in that it comes in a very small plastic. Minor ironing! A good buy!!

Very nice jacket/coat for the price
Size: X-Large, Color: Black
This was purchased to wear with a tuxedo for northern winter wear. The size XL is what he normally wears. It fit well over a tux shirt, vest and jacket. The length is perfect for a man; it covers the tux but does not get tangled in knees. It is lined in a satiny fabric. The wool type material is a bit rough, not soft, but it does the job. The black is rich looking and provides warmth for really cold weather. This jacket can easily be worn for casual wear. Should only be dry cleaned, but doubt it will ever really need to be cleaned.

Actually violet color and looks nothing like picture
Size: Large, Color: Red
Bait-n-switch. What arrives looks nothing like the photo. Its purple/pink and a misshapen ladies coat. Really low quality. And why they make them 90% polyester is crazy - just waiting to explode in flames!
