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.

Comfortable Fit without over compression
Size: 38B, Color: Gentle Rose
This is a good post surgical bra. I had a lumpectomy and it gave me enough support without being too tight. It is adjustable in the front and the shoulders. Use the size chart to get your best fit. Soft material. Comfortable enough I wore it 24/7 for a couple days. Only downside is handwashing but I will try the delicate cycle on my machine and air dry always.

Awesome bra!
This bra is so comfortable. I love the fact that you can adjust the straps and the front to make it fit a short person's torso. This bra lifts and so far, has not stretched out.

Soft and Comfortable
Size: 46D, Color: Black
Size 46 D, black. Very Comfortable ! The strap adjustments are in front so it would be easy for someone who needed a caregiver to help them dress. The cups fit well with no gaps or wrinkles and the back lays smoothly, with no irritating seems or crossovers. The chest band is one piece, so no irritating seams, and its a little more supportive than my usual at home or bedtime bras. I tried it on and decided to wear it an hour to see if it stayed comfy while I moved around the house. It was so comfortable I forgot to change it! I ordered the black and when I machine washed it there was no dye bleeding. Hung to dry. Wearing it again and I think it just might become my new favorite. If I still love it, I might purchase another color in next month's shopping budget.

Extremely Comfortable
This bra is the most comfortable bra I have worn. It is so comfortable it doesn't even feel like I am wearing a bra. There are no unfinished seams inside. I like the fact the shoulder straps are hook and eyes that don't slip like the conventional straps. This bra is reasonably priced and nicely made with good support.
