Series 40 Orbit BB Quad 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

Perfect Drawer Organizers—Love the Assorted Sizes
Color: Clear
I really love these drawer organizers. The quality is great, and the assorted sizes are exactly why I decided to purchase them. I used a few inside my vanity to help keep everything more organized, and they work perfectly for separating smaller items without everything getting cluttered together. I like that there are multiple sizes included because it makes it easy to customize the layout for different drawers and products. One feature I really appreciate is the non-slip bottom. They stay in place well and don’t slide around every time I open and close my drawers, which makes a huge difference. The clear plastic design also makes it easy to quickly see where everything is without digging through the drawer making a mess. They feel sturdy and durable, not flimsy like some other organizers I’ve tried. I also like that they can be stacked when not in use, which helps save space. Best for: vanities, makeup organization, bathroom drawers, office supplies, and general home organization Overall, these are practical, well made, and really help make drawers look cleaner and more organized. Definitely happy with my purchase.

Clear, Stable, and Surprisingly Better Than IKEA
Color: Clear
I didn’t expect to be this impressed by drawer organizers, but the Vtopmart 25 PCS Clear Plastic Drawer Organizers really delivered. The non-slip silicone pads actually work — once placed, the trays don’t slide around at all, even when opening and closing drawers frequently. That alone makes a huge difference in daily use. What I love most is how much space they save while keeping everything clearly visible. The clear plastic makes it easy to find what I need at a glance, and the variety of sizes lets me customize each drawer instead of forcing everything into awkward layouts. All the organizers have a solid, usable depth, so items don’t tip over or feel cramped. Cleaning is effortless — a quick wipe and they look new again. Compared to IKEA organizers I’ve used before, these feel more practical, easier to maintain, and honestly more flexible. Add in the great price for a 25-piece set, and this feels like one of those simple purchases that quietly makes everyday life more organized and less frustrating.

nice set
Color: Clear Black
I bought this set to organize a messy desk drawer and it made a huge difference right away. Having multiple sizes in one pack is what really makes this set useful. I was able to customize the layout instead of trying to force everything into a few fixed compartments. The trays feel sturdy enough for everyday use and the clear design makes it easy to see everything at a glance. I used them for things like pens, paper clips, chargers, and random small items that usually get lost, and now everything actually has a place. They also don’t slide around much once placed, especially if the drawer is fairly full, which I appreciated. Setup took just a few minutes and instantly made the space look cleaner and more put together. If I had to note anything, the plastic is lightweight, so it is not heavy duty, but for organizing office supplies it works perfectly fine. Overall, a really practical set that helps you stay organized without overthinking it.

Great organizers!
Color: Clear
This is a really practical organizer set. I used it in my bathroom and nightstand drawers, and it helped clean everything up fast. The different sizes are the best part—you can mix and match depending on what you’re storing. Only reason I’m giving 4 stars is because the plastic isn’t super heavy-duty, but it’s still perfectly fine for everyday use. Good value for the amount you get.
