Series 40 Orbit RT Triple Block with Becket, Cleat & Swivel

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 also 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 extremely 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

Too stretchy for my preference
Color: Black, Size: Large
The socks seem to be high quality, but they are too stretchy for my liking. They feel like "compression" socks, and become too thin and stretched when worn (yes I bought the correct size). Even though they have less Spandex than my preferred wool socks (e which are no longer available), they are much stretchier.

Thick and comfortable
Color: Black, Size: Medium
These socks fit 7.5 wide size woman's shoe wearer perfectly. Socks are thick and comfy. They stay in place all day. I got rid of all my old socks and it is a pleasure not having to scrounge for a matching pair. They wash and dry well in machine on wool setting.

Very pleased!
Color: Black, Size: Medium
Good fit, good thickness, keeps feet warm and dry, no uncomfortable seams. I've only washed them twice, but will return if items don't hold up. So far they're proving to be a good investment.

Garbage socks.
Color: White, Size: Medium
After wearing a couple times there is a hole in the heel. I think they're made of tissue paper;

Great
Size: Medium, Number of Items: 1
I need something that was soft for my three year old and this ball is super great, it not only is the right size but it also fits in his mouth just right. Although he is a super aggressive chewer, the ball toy hasn't been totally destroyed yet and it is easy on his gums. The ball is so durable that got two of these toys just for fun.
