About This Product

Hercules 1-1/2 in. Rebar Chair is a patented polypropylene support system ideal for concrete applications requiring a 4 in. to 5 in. slab, including floors, sidewalks, driveways and many others. Unique fastening system ensures accurate positioning of rebar, to code, during concrete placement. Designed for #4 rebar, the #911 has 1-1/2 in. clearance from the ground to bottom bar. Simply snap the rebar into place. No wire tying is necessary, saving time and labor. Allowing maximum concrete flow in and around the chair, #911 is your solution to get the job done right.

Highlights

  • Polypropylene chair has 3-1/4 in. x 3-1/4 in. base, a strong support that will not collapse during pour
  • Designed for use with #4 rebar (1/2 in.), chair measures 2-3/8 in. from ground to top of highest bar
  • Meets requirements to qualify as CRSI class 1 bar support
  • When snapped into chair, rebar is properly positioned with 1-1/2 in. clearance
  • Wire tying is eliminated, cutting rebar placement time by 1/3, leading to increased profits
  • So strong, workers can walk on grid during pour
  • Maximum concrete flow reduces job time
  • Bottom rounded edges and flexible corners minimize puncturing of under slab vapor barrier mat
  • Use our estimator and placement guide to calculate quantity of this product needed for your project

Q:Do you have to thread the bottom rebar through first, if 10 feet how many chairs to slide in?
by|Aug 11, 2023
1 Answer
Answer This Question

A:  The pic is deceptive. The chair is open to the bottom and top. I recommend twisting the chair onto the #4 rebar first (#3 drops in), then twisting the #4 rebar into the top of the chair (again #3 just drops in). While you can muscle # 5 into the top position only, I don't recommend it. To be clear I don't mean screwing, you just need a 1/4 turn to get the lip of the pocket past the ridge on the bar. After a full length of bottom rod (bar) is laid I go back and adjust the chairs to sit flat & properly spaced. With practice, you can set (twist/untwist) the top rod (bar) without having to go back. As far as how many you need, that depends on your matrix (grid spacing), which is either by spec.(plans/engineer/table/etc.) or by governing body (code/inspector/etc.). Unless you have (or access to) a machine that ties rebar together, I highly recommend these chairs (appropriately sized for your project) over wire chairs. They take a little longer when first using them, but you can quickly learn to not break them and be efficient in placing them. I find them to be an excellent way to keep hydronic lines closer to the surface instead of wasting precious BTUs heating the ground.

    Q:Will this product work with wire mesh?
    by|Apr 9, 2022
    6 Answers
    Answer This Question

    A:  I don't see why not. It's designed to hold rebar, but if the mesh sits symmetrically at a 4-corner point on the stand, it will certainly support the weight. Your goal with these is to just suspend the structural supports (whether rebar or mesh) from sinking to the bottom of the cement when it's being poured.

    by|Apr 14, 2022

      A:  I doubt it would work with wire mesh. I think walking on the mesh would collapse the chairs. With rebar you can kind of walk inside the grid.

      by|Apr 11, 2022

        A:  No.

          A:  It's designed for rebar but you could drop mesh on them. I personally wouldn't use them again. They are too tall and too fragile.

          by|Apr 13, 2022

            A:  I was using rebar, but I'm sure it would work with wire mesh as well.

            by|Apr 12, 2022

              A:  It is made for reinforcement bar.  It could hold up wire mesh if you used enough of them and spaced them so the mesh does not sag.  You would have problems if you walk on the mesh!

                  Q:Pardon my ignorance; I have never worked with concrete and am researching. The product description and installation guide did not explicitly say that they get buried in the concrete but sort of implied it by saying that they are strong enough to hold up during the pour. Just want to verify whether or not these stay in the mix even after it’s poured.

                    A:  They get buried in the concrete. They hold the rebar in place during the pour.

                    by|Feb 12, 2021

                      A:  They stay in after the pour to make sure they stay in place while the slab cures.

                      by|Feb 13, 2021

                      A:  Yes, they get buried - they are designed to lift up the rebar and tie wires off the ground so you get proper centering in the thickness of the pour. Note - you use the right model for the thickness of your pour.

                      by|Feb 14, 2021

                      A:  They get buried in the concrete. You may want to check out the concretenetwork web site and the "Technical Information" tab.

                      This is a great product and makes adding rebar quite simple. Suggest it be stocked locally.

                      I like these rebar chairs, but getting rebar snapped into it can be a little difficult if the rebar isn't pristine. Even with some surface rust on the rebar, I found that whacking the rebar right next to them with a framing hammer generally popped it into place, but occasionally the rebar would hang up on the plastic and want to bend the top of the chair rather than snap in. Occasionally I had to slip a screwdriver or other thin object in to spread the chair opening to be able to get the rebar in, so a little more taper on the gozinta plastic would probably help. Otherwise, though, they are sturdy and keep things nicely spaced. I found that placing a chair at every other intersection worked great, plus it saved a bunch of chairs and was still plenty strong. The attached phot shows a recent project - a concrete ceiling for a vault.

                      Tore up a sidewalk that was not level (erosion) and a small slab that was broken. Very easy to set. Used 3/8" rebar that worked just fine.

                      These Hercules 1-1/2 in. Rebar Chairs worked out great for us. I would use them again. The rebar can be tuff or tough :) to "snap" into the holder. BUT, we learned quickly ROTATE the rebar as you attempt to snap it into the holder. This made the job much easier. Other than being tough to snap they are great. Yes, I would recommend. Thanks - Stone

                      Ordered, arrived and installed and worked as expected. Yes you could walk on the crossed rebar and not break or move them as we poured the concrete. Thanks Home Depot!

                      Idea is great as a alternative to tying hundreds of overpayments but didn’t hold the rebar very well and of course didn’t find this out until we started pouring. Luckily we had ties and were able to secure most of the mats but won’t make that mistake again

                      Super Strong and made in the USA. These were awesome for placing rebar without ties. I used these on top of a vapor barrier and ridgid foam. The wide base never punctured the vapor barrier or pushed into the foam. They stood up to 5 men walking all over them while placing the concrete without a problem. My rebar and tubing was held firmly in it's proper place
