Q:If 2" chair is stacked on top of 2" chair what is the total height of them two? I am assuming more then 4". How tall?
by|Oct 27, 2022
1 Answer
Answer This Question

A:  The chairs are 2" but the total height will also depend on the size of the rebar itself. Add them up and you'll get the total height.

    Q:If using these for mesh support what becomes of the extra length on top that would have been used to lock criss crossing rebar? Do you cut it off, or leave it and if you leave it doesn't that weaken the concrete if I have a 4" slab to pour?

    A:  These are trash. They fall over and drop you mesh rebar as you pour. Just pull your mesh rebar up as you pour. You're going to have to do it anyways.

      A:  The mesh can be left as is or cut it off, but it shouldn't weaken the slab

        The rebar chairs worked well. I used them over Styrofoam insulation . I used 120 of them on a 26' by 30' slab poured 5 1/2" thick. I found that they set the rebar higher than you think it will from the 2" description. I had initially installed 3" chairs but they were way too high.The chairs are very expensive and according to my concrete finishers not often used. That being said they liked them . They stepped on the rebar several times without harming them.

        2" Chairs are not suitable for 4"-5" concrete. Maybe 6"+ pours. Easy Installation.
        I bought several packs of these in-store to allow me to add 30 sticks of Rebar into a new garage slab I was having poured the next day (I ended up needing 65 total, 1.5 packs). I got them installed so they're holding both the mesh AND the rebar up, which was pretty cool, and the installation was really straightforward and easy! However, what they don't tell you is that the 2" height measurement is from the base to the *bottom* of the first piece of rebar. That means on this 2" model that the top of the upper piece of rebar is over 3" from the subgrade, which is unsuitable for a 4" thick floor slab. The rebar needs to be in the bottom 1/3rd of the concrete (in the bottom 1.5"). With these in the 4" slab we were pouring, we would only have 3/4" of concrete above the top rebar in most places, which is unacceptable. The contractor and I had to rush like madmen to pull all these rebar chairs back up before the concrete truck arrived to pour. We ended up using old fashioned metal wire ties to link the whole grid together, and then stood them up half an inch on tiny chunks of dried concrete to make sure that they'd be in the bottom of the pour. The concrete contractors said that these rebar chairs were a great idea, but the execution and labeling of the product was very poorly thought out. To get the rebar in the bottom 1/3rd of the slab, a 1" chair would been perfect for a 4" slab, a 2" would be good for a 6" Slab, and a 3" for something crazy thick like 8"+. The unused chairs will be going back for sure, and I plan on asking at the customer service desk about the ones I did use - the fact that they're labeled for use in an 4" slab, but can't actually do what they say they will is a little bit of a pain!

        Solid and well designed
        These actually work with both #3 and #4 rebar unlike the cheap ones. Holds the rebar real steady and they do not sway around because they have a firm grip and the rebar actually help steady the base. It even hold bent upward rebar in place (photo posted), used to secure a wall to its poured footing. A bit pricy but you will save yourself a lot of time and headaches trying to get the bad ones to work and often failing. I have not tried these with mesh yet but I expect they will work great for those. If you are doing a reinforced patio the design of these will hold the rebar and mesh all it once. The price can add up quick for a big project but they will save you a lot of time as well. If I poured for a living I'd never bother with those cheap versions. You'd waste too much time fixing them.

        I had a very small job, so they worked out great. I just had to put a little effort into pushing the rebar in, but nothing too strenuous.

        Not impressed. Some broke while snapping the rebar in place. Many fell over (more than once) before concrete was poured.
