Series 40 Orbit BB Cheek 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

Very good, helps with pcos acne and dark spots
I have pcos, so my acne and dark marks from acne can get pretty severe, in one use there was a visible change. It doesn't have an intense fragrance. It doesn't make my skin feel heavy, sticky, or greasy. My skin feels healthier and holds moisture better. It has a good amount of product in each container. I'd say its definitely got a good amount of value for the money.

Good Molecule
I tried their one product once and it was very good, so when I saw the set range - I definitely had to get it. A great set introduction to this line of brand. It’s light, it works and the price bracket is friendly on your wallet.

Hydrated & Bright: My Good Molecules Review
​I recently overhauled my daily skincare routine with a full lineup from Good Molecules, and the results have been nothing short of wonderful. I've been consistently using their cleanser, toner, hyaluronic acid, Wakeup Eye Gel, and daily moisturizer, and my face has completely transformed. Overall, my skin feels incredibly soft, looks noticeably brighter, and stays perfectly moisturized all day long.

Good combo for the price
I have eczema which causes me to have very dry skin. I have been using this for 3 weeks and only had 1 breakout which I don’t think correlated. I did go in with extra moisturizer on top of the moisturizer that is included.

Great product
Love this product! I've always struggled with acne as a teen and even now that I'm 32. I've tried other products like the more expensive stuff but i see no results and with this I've had success and will continue to use!
