Product Details

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.
  • 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, located on this page under Info & Guides/Installation Guide

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. 

      by|Apr 13, 2022

        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:Do these get buried in the concrete pour or do they have to be taken out during the pour so the rebar is “floating” in the concrete mix?

                A:  They get buried in the concrete

                by|Feb 14, 2021

                  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.

                    Q:Does the top steel finish at 1 1/2 inches from the base or the bottom steel

                    Answer This Question

                    A:  The top bar sits at two inches high the bottom one is at one and a half high

                    by|Oct 15, 2021

                      A:  These are optimized for a 4" slab: the bottom of the lower rebar is 1.5" from the foot, the intersection of the two lengths of 1/2" rebar is therefore at 2", and the top of the upper rebar is at 2.5".

                      by|Jul 22, 2021

                      A:  The 1 1/2 " Clearance is from the ground to the bottom of the lower bar.

                        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

                        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

                        Th 1/2" rebar used snapped right in and held tight. As I was using materials on hand, like wire mesh, I ted that over the rebar. Chairs worked great, just the right height for my concrete depth with the radiant tubing on top. Also used it in a short drive with 3/8" rebar. Still worked good for height, but had to wire tie those pieces as expected.

                        Worked very well and easy to use
                        These were listed as being 1 1/2" chairs, however, the 1 1/2" height is at the top of the lower rebar in the chair. When used to cross rebars for a square grid, the top of the upper rebar is at 2" above the base of the chair. I was pouring a 4" slab so the 2" was OK, but I would rather see them market the product using the upper rebar dimension. Seems to me that would be the most important dimension.
