Question: Can I use 2 by 6?
Document: This system allowed me to build a basement storage unit that was 8ft wide & 8ft high with 4 shelves that can store about 20 total Rubbermaid containers (18 inches between shelves)! I used 8 total shelf links and 20 2x4s (~$3.00 ea). Using a hand circular saw it's tough getting the middle pieces cut by exactly 6 7/16" and instead mine are more like 6 1/2".
This is a great product. I used two sets (i.e., two sets of 6), to make three sets of shelves, each with 2 shelves.It's useful having an extra hand when putting these together, in order to get the shelves all level.I have recommended them to several people. Another related product that's great for unfinished basements is the 24" wideQuick - Shelf Hangers Overhead Ceiling Mount Storage Unitand the 16" wideQuick - Shelf Hangers Six Shelf 16" Deep Ceiling Mount Shelving Unit.
If you like the look of 2x4's with black plastic connectors, then maybe this is for you. However, please notice how easily the 6 black plastic connectors could quickly be replaced with 6 short pieces of 1x3 lumber, to make the same shelving unit. You already have to cut 2x4's to use this system, so cutting 1x3's shouldn't be a problem.
I used deck screws for those.Awesome product, will use again for sure. Matter of fact I already bought 2 sets.
30 5 star reviews? I am confounded, but that suckered me into buying these things. Here's why I gave a 2 star review:1) You are forced to build a shelf that is 16" deep. In my opinion that isn't very deep for a storage shelf.2) You are forced to lay the horizontal 2x4s with the wide face up. You never use the wide face of a 2x4 for structural support.
My husband purchased these shelf links to help organize our garage. We just moved into a brand new house and there are more homes being built all around us. He got the idea of dumpster diving to recover discarded 2 x 4's and use them to make a shelf for storage in the garage. He used these shelf links to piece the shelf together. I was really impressed. The shelf is large, strong, and not an eye sore. He is considering purchasing more because of the versatility of this item.
No small stuff on these shelves.4) And this is what really gets me: You are forced to use 2x4s to create the shelves themselves. This just waste trees and money and isn't that strong. These things force you to use a ton of lumber!Just use 2x4s for the cross members instead of these. Run (2) horizontal 2x4s with the short face up and lay down 3/4" OSB or plywood.
The old metal/steel shelves rotted and collapsed in our basement (though we had no moisture down there) after several years of use. We purchased several of these kits and some 2&#34; x 4&#34;  fir and made enough shelving in the basement to store lots of heavy boxes, tools, paint, luggage, etc. These shelves are very strong; even the longer spans could hold a lot of weight.
We have purchased 6-8 sets of these within the last 10 years. They are an excellent way to make strong, heavy duty shelving for approx $35/shelf (9' lengths) including the studs! The ones we bought 10 years ago are just as good as the ones I purchased this year. I definately recommend these!
I'm planning to put together Some shelving to get all my books in one place while doing some home renovations. My local national hardware chain (the blue one - didn't check the orange one yet) has these for $5 le$$ per 6 pack. I was surprised. I was really just trying to put eyes on them to see if they look as good in person. They do.
