SandbaggyRebar Plastic Chair | Fits Rebar #3 to #5 | Heavy Duty Construction- Preferred Choice for Concrete Contractors | Saves Money & Labor Compared w/Dobie Bricks (Pack of 100, 3-1/4 Inch Length)

Good product,could possibly use a wider base but not too bad at all

Overall, these chairs don't have much base. Setting them is a bit problematic as they kick out as you move along. Would not buy again.

They are durable, light and can withstand the heat

These plastic rebar chairs might work great when placed on a sand base, but they are very tippy when you try to seat them on a gravel base or any other uneven surface. Pour a trowel worth of concrete around each chair manually to stabilize the chair before pouring concrete into the rest of the form.

The base on the stands is too narrow and they like to rack and tip over. Also, the plastic is weak is the side wings buckle. Though these would save time and money but found that the concrete dobies were cheaper and far superior.
