Series 40 Orbit BB Quin Block with 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
  • Low friction 2-stage ball bearing system for efficient and effortless trimming

Potential Fall Risk
Size: 2 pairs black L
While these socks do indeed help soften rough skin on your feet, there is a risk of falling while wearing them. Although they have treads on the bottom, which would indicate they’re safe to wear with nothing else, when you put moisturizer on and then wear them your foot can slip inside the sock . This causes you to lose your balance and fall, which happened to me. I’ve thrown them out.

I could be a foot model now!!!
Size: 1 pair black L
I wear work boots almost all of the time so I bought these to put on my feet with salycylic acid to moisturize and try to get rid of a stubborn corn on the ball of my foot. It helped drastically after a few nights of lounging in the house with them on.

Stains easily. Tight for men's size 11 feet
Flavor Name: XL silicone socks 2 pairs, Flavor Name: XL silicone socks 2 pairs
Husband wore dark cotton socks over these gel foot covers overnight and the covers picked up color from the socks. Tried hand washing, even dabbing with a bleach soaked paper towel, but the stains remained. The covers are a bit tight for men's size 11. Edit: After a few more hand washings the stains began to fade. However one tore around the leg opening when taking it off.

Worthless. Tore on first use.
Flavor Name: XL silicone socks 2 pairs
The first time I put these on my feet, the whole toe broke right through. They were a proper fit and my feet are well pedicured. Just very poor quality. I don’t recommend.
