They work fine with 3/8" we did. of course they don't grab the bar tight but you can tie em to the chair if you feel it's necessary. This chair is more stable than any others I've seen.

Customer Reviews

Rated 4.7 out of 5 by 10 reviewers.
Rated 5.0 out of 5.0 by Hercules re-bar chairs This product saved 10's of hours in setup and tying re-bar. I only wish it was stocked at at least one store in a major metropolitan area. Ordering online is a pain. June 22, 2015
Rated 5.0 out of 5.0 by Great product Great product. Might want to use a concrete vibrator to make sure all the concrete is in and under them. Easy to use, and can walk on the rebar. A+ September 2, 2014
Rated 5.0 out of 5.0 by Rebar Chair Saves a lot of time over using wire to bind the concrete screen. Good product, wish I had them 20 years ago. December 8, 2015
Rated 3.0 out of 5.0 by not good for radiant pex when fastening to rebar would be ok otherwise but they really get in the way of attaching pex to the rebar, you have to swing the pex around the chair or put it right on top which may put it too close to the top of the concrete. November 8, 2015
Rated 5.0 out of 5.0 by rebar chair really worked to hold rebar in place to pour cement.strong saved me time and labor cost November 11, 2015
Rated 5.0 out of 5.0 by awesome Just poured 15 yards of concrete for a driveway. Spaced 1\2 inch rebar every 18 inches and these chairs are the best. Saved me many hours, highly recommend. September 2, 2015
Rated 5.0 out of 5.0 by Best Re-Bar chair on the market These worked awesome, I would never use anything else. September 2, 2014
Rated 5.0 out of 5.0 by Easy to use! The Hercules 1/2" rebar chairs really made it easy to lay out the rebar for a slab I'm preparing to pour. The nice thing is that, with the 14" grid spacing that I used, I was able to place a chair at alternating rebar crossing joints and still hold the entire structure off the ground. I did wire-tie the joints where I didn't place chairs, but no ties were necessary at the chairs; the rebar just snapped into place. September 14, 2013
