Product Information
The new Series 40 ball bearing Orbit Blocks™ provide 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 fibre 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 are adjustable for setting to 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.

Spinnaker sheets on dinghies, off-the-beach catamarans and sportsboats to 8m (26ft)

Glitter Bomb
Color: Glint Rainbow
It gets ALL over the place and doesn’t stick all that well. Neat idea but it doesn’t work the way I would hope.

Great glitter body spray
Color: Fairy-Diamond, Color: Fairy-Diamond
So cute. Came with extra glitter, I’m assuming lipgloss you can make into glitter lipgloss, a funnel to help pour the glitter. Or re load your spray. The spray performance is nice. Might stick better with some oil before hand? But I like it so far. Worked 6 hours and still had glitter on me for my photoshoot. I sprayed perfume and then glitter. There’s no odor. The amount of quantity of glitter you get seems good for the price. Durability seems good so far but like I said may need some oil or lotion first to help it stick all day.

Troll glitter
Color: Brandy-Rose
Do not spray too much! This glitter is so fine that it dispenses easily from the puff part and you can easily make yourself look like Poppy the troll. We had so much fun with this for prom

Glitter with staying power
Color: Rainy-Rainbow, Color: Rainy-Rainbow
Super fun and sparkly, the color is beautiful, it comes with 2 glue tubes with brushes that you use to rub the glue onto your skin in order for the sparkle to stick better and longer, made a heart shape on my arm, dries fairly quickly and washes off easily when you're done with it
It sprays a fine layer and evenly, it's great for building on for more sparkle or to just have a light layer
Even without the glue it lasts at least a couple hours with minimal shedding and light use, seems to have good longevity
With 2 glue tubes, a refill tub, funnel and the glitter spray bottle I feel $10 is a great value considering everything you get with it, Overall I feel like it's a fantastic product and will buy again!
