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.

Features:

  • 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

Great little sealer!
Size: Vacuum Sealer + 30 Bags
The vacuum sealer is wonderful, takes up very little space in the drawer and does an awesome job. We looked at some videos before we decided which one we wanted to buy. The best tip is when you are using the sealer try to have that area flat with no food under the sealer area. Love it that the bags are reuseable!

Good alternative to a full size vacuum sealer
Size: Vacuum Sealer + 30 Bags
This vacuum sealer is great. I had been reluctant to invest in a full size vacuum sealer so this was a great alternative, I’m totally sold on the versatility and ease of use. The included bags are a little tricky to close at first but they get easier to use as time goes on. The suction is sufficient for what I need (mostly storing meat bought in bulk in smaller portions in the freezer) and the bags definitely keep things fresh while preventing freezer burn. Despite the low price point the durability sees good so far with over a month of near daily use.

Great Sealer for the Price!
Size: Vacuum Sealer + 30 Bags
LOVE this portable sealer...and I own a bigger Vacuseal that I purchased from Costco. When you need a "quick and easy" sealer for foods, this works and is easy to use. It doesn't require space and I like the simple look. The bags are reusable (need to wash them) and are good quality. Just make sure that you "zip" the seal completely. Great sealer for the price!

A good tool to help extend shelf life of fresh food!
Size: Vacuum Sealer + 30 Bags
I have had this for 3 months. I love it! Bag is sturdy and easy to clean. It freezes well-food is not getting freezer burned. In the fridge, fresh veg lasts longer. Compact and easy to store/use. It takes a bit of practice to get the suction right-and sometimes sucks so much it crushes soft food. But, It has saved me from throwing out food that goes bad--extends fresh fruit and veg for several days. Long battery life.
