Product Information:
Lightweight
Kilogram for kilogram of working load, BB and RT Orbit Blocks™ are the world’s lightest. The unique orbital design allows the bearing to only be in the active areas of the floating sheave. This minimises the mass of the inactive return race and hub.
Weight and bulk are further reduced in the different block configurations. The ball bearing single and becket block has a through-sheave becket arrangement. The result? The lowest weight possible.
Multi-sheave blocks have only single intermediate cheeks and an ultra-light and efficient head arrangement. This gives a 30% weight saving advantage over the nearest competitor. Other brands just link together their single blocks. This results in unnecessary double cheeks between each sheave, held together by a heavy steel channel across the top of the block.
Highest working load in its class
The orbital ball-bearing arrangement gives the largest possible bearing race diameter. This maximises load performance. The proven Ronstan 2-stage bearing system features high compression grade acetal ball bearings and a secondary full-contact bearing. This gives minimum friction across the full working load range.
The floating sheave and bearing system is supported by a fibre-reinforced load frame. The design was computer modelled to be stress optimised. The Dyneema® Link is produced from FSE Robline SK75 fibre, which is 10 times stronger and lighter than steel, and provides the final connection from the block to the load point.

Mainsheet systems on dinghies, sportsboats and small keelboats to 9m (30ft)
Spinnaker sheets on dinghies, sportsboats and small keel boats to 9m (30ft)
Halyard, Vang and Backstay application on boats to 8m (26ft)
Control line applications on larger yachts

Love these!!!
Size: 42inch Tall (NOT included wood planks), Color: Black
Super sturdy..looks excellent. Industrial and clean lines....lots of space for our kids bathroom. The wood does not come with it but was easy to get lowes. We actually added another shelf on the top bracket to make 4 shelves. They're nice and wide to fit baskets and organize things. For teenagers bathroom! My husband installed by himself and he isn't the handiest of guys but it it wasn't bad. I do recommend getting pipe fastners to secure the boards to the pipes so they don't shift around

Nice pipe shelves! Excellent quality!
Size: 28inch Tall (NOT included wood planks), Color: Black
I really like the fact that the pieces were already painted. I compared the cost of the unit to buying the pieces from the big box store and this was far more cost effective for me.
The installation went well and I ended up creating a template for installation. For the template, I measured the width of one of the flanges (part that mounts to the wall), cut a piece of material the same width. I found the center and drew a line down the middle. I then placed the section with top and bottom holes over the center line and then marked the other two holes.
I then drilled out the holes, put on wall and used level to plumb. I used small pilot drill bit to drill through the template into the wall.
One thing to note is that I did not use the included anchors instead opting for some from the big box store.

Well built and priced
Size: 42inch Tall (NOT included wood planks), Color: Black
I saw these on line and decided I could probably just build one on my own. After pricing the parts out at the local hardware store, it was almost the same price, and opted for the less hassle pre-fab online kit. The material is well made, same as the hardware store, except the threads are shorter for easier assembly, and its painted for a cleaner look. I bought the 12"Dx42"L kit, and although I knew the measurements, it was a lot more massive than it looked in the picture. An 8' or 10"x 24"L kit would have fit my needs better. I only assembled 2 of the 3 sections, and will use the single section leftover for another shelf elsewhere, so it wasn't a problem. I'm happy with the end result and would recommend.

So beautiful!
Size: 42inch Tall (NOT included wood planks), Color: Black, Size: 42inch Tall (NOT included wood planks), Color: Black
The poles are very sturdy. The order doesn’t come with wood but I only spent ~$15-20 on the wood and stain needed to shelve the poles. The only complaint I have is it was hard to install; mostly due to my lack of experience. It took most of the day to install and stain and cute the shelves. The poles weren’t completely flush to the wall and I couldn’t figure it out for the life of me. I love the way these turned out and I know these shelves will be coming with me to the next home I have. 10/10 would recommend, even with the hard installation. SO worth it.

Strong legs, somewhat industrial but trendy also
Size: side table leg
Good legs, some what utilitarian or industrial, they are strong as they are made out of pipe, and assembly is fairly easy once you get the idea of how it goes together. They are roughly 1.5 feet across maybe a bit less adjustable height on each leg, if you have wood floors you may want to put a pad under each leg as they are full metal pipes. Pretty interesting idea and does not cost much.
