Customer Questions & Answers

Does this product accommodate #4 and #6 rebar?

I need a 3" rebar chair for a vertical wall, and it must accommodate #4 and #6 rebar.
Asked by: Richard
Seeing how the product description says its for 1/2" (#4) AND 5/8" (#6) rebar I'd say this will work for you.

While building our deck, the engineer called for #5 rebar in our 18x18x16 footers. These chairs made the installation so simple and easy. This is the only chair I could find to hold a #5. I wish these were in the stores as well as online. All the other chairs in the store were for #3 or #4. I did not need to tie the rebar and the rebar just popped in the slots. Plus it was also easy to readjust while the rebar was in the chair. I was able to build 15 9x9 pattern frames for the footers in about an hour. The rebar cutting took longer. I am very happy with the product. I also came up a few chairs short and called hercules direct and their customer service was excellent and they helped me acquire a couple of single chairs to finish the job. Thanks Anthony!

Rated 5 out of 5 by from concrete driveway project The Rebar Chair that i purchased from The Home Depot was an exceptional value product. It saved me time and money. The rebar chair that i used for my concrete driveway project was a 3 inch chair , but is also available in two inch chairs, made the task of setting up the rebarbs in a cris-cross pattern mad it so simple and fast without the hassle of tying rebars together jus t press down and they were locked in place, to set 250 rebars on chairs took approximately 2 hours with two guys doing it , amazing product!

Rated 5 out of 5 by from Labor & Time Saver I purchased these Hercules 3" chairs for a home concrete project. The crew doing the concrete work had never seen these items. They were very impressed with the way they were able to configure all the rebars in place so quickly. All rebars snapped into place requiring very little ties.

Rated 5 out of 5 by from Hercules Rebar Chairs Very strong as advertised... The Rebar chairs have a good foot print to be very stable once the 1/2" or 5/8" reinforcing bars are crisscrossed into the saddled holders..

Rated 5 out of 5 by from Great if you need 3" off the ground and have fairly heavy rebar I ordered these cause I couldn't find anything locally that would suit my situation. I had a lot of #4 rebar in my footers and the engineer called for 3" clearance. These were easy to use and took the weight with no problem. Not real cheap, but not super expensive either.
