Series 40 Orbit Single BB Single Stand-Up Block

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
  • Soft attachment, lashing, and traditional swivel shackle head options

Not bad for the price point.
Scent: Unscented, Size: 8 Ounce (Pack of 1)
I don't mind this product; it's well-priced; however, in practice, it was slightly too oily. I prefer other beef tallow products, or even just straight-up beef tallow, rather than this product. Because I have severe eczema on my hands, I prefer tallow blends that have faster absorption. However, this product is perfectly suited for use as a night moisturizer or as a hand mask. I would probably buy this again if the formulation were less oily/greasy next time.

Exactly what I wanted and more
Scent: Unscented, Size: 8 Ounce (Pack of 1)
No odor, slightly greasy but thats to be expected. I apply it on my face before bed. I live in a dry desert so this is amazing for my skin. Within a couple days my skin looked glowly and hydrated. I even feel like my very fine lines are less noticeable (I'm only 27). My husband even commented how good my skin looks and he has no idea I even switched face moisturizer. I have sensitive and dry skin so I am very pleased. I wake up feeling great with this product. It's a heavy balm but I expected that so I really don't mind.

Not sure
Scent: Unscented, Size: 8 Ounce (Pack of 1)
Initially it has a very greasy feeling and takes quite a long time to absorb. Once absorbed it feels very nice. It is a very nice thick tallow, quality seems very good.

Moisturizing
Scent: Unscented, Size: 8 Ounce (Pack of 1)
A little goes a very long way with this product. It feels amazing and makes my skin so soft. It pairs well with my snail mucin. My skin looks beautiful. Just be careful not to use too much copilot said it can cause breakouts but I’ve been using it every other day for a week now with no break outs. I also pair it with a beef tallow serum.

Sand paper residue
Scent: Unscented, Size: 8 Ounce (Pack of 1)
I ordered this in march just started to use it. I’m not sure if I got a bad batch according to reviews, however it’s like rubbing on sand paper it leaves a white residue on your skin . After it heats up you can rub most of it in but I wouldn’t reorder. It does moisturizer but the sandpaper feeling is not worth the trouble. :(
