Sandbaggy Rebar Plastic Chair | Fits Rebar #3 to #5 | Heavy Duty Construction - Preferred Choice for Concrete Contractors | Saves Money & Labor Compared w/Dobie Bricks (Pack of 50, 3-1/4 Inch Length)

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.

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

Not stable at all

They are durable, light and can withstand the heat

These chairs do not work nor is their any method, adjustment, alteration, or scenario which can make them work. I don't know how there could be any legtimate positive reviews of this product. I ended up purchasing concrete dobies and these are in my trash can.Think of these as manufactured by a chinese company that saw a photo of concrete chairs and produced something that has a similar look but never tried to use them,

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.

look great before pour. do not stay in position during pour.

If you want your bar to stay up when pouring buy something different. I’m throwing them out.
