Zero-Tie Rebar Support. Designed for 4 Parallel Bars.

4-Bar Footing Chair

Master Massive Foundations with the 4-Bar Footing Chair

The Synchro 4-Bar Footing Chair is our most expansive trench support, engineered specifically for your widest and heaviest deep foundation pours, including massive commercial grade beams, extra-wide perimeter frost walls, and heavy grain bin pads. Designed for raw, uneven dirt trenches, this heavy-duty steel chair accomplishes what would normally take four separate, flimsy single-wire supports. With pre-welded, exact factory spacing that perfectly holds four parallel rebar rods, your crew can permanently put their tape measures away and reduce foundation prep labor by up to 70%.

Multi-Bar Support (3-in-1)


One chair replaces three. Synchro’s chair spans the width of the trench, holding 3 parallel bars simultaneously with a single drop.

Automatic Factory Spacing


Pre-welded exact spacing at our automated 3D CNC factory completely removes human error and the need to lay tape measures in the mud.

True "Zero-Tie" Capability

The specialized 1.5-inch deep lock slots trap the heavy rebar naturally, completely eliminating the miserable job of hand-tying wire.

4 BAR FOOTING CHAIR PLACEMENT & USAGE

Designed for extra-wide dirt trenches and heavy grade beams, the Synchro 4-Bar Footing Chair offers an incredibly fast "drop-and-pour" setup. Workers place the pre-welded chairs directly into the raw dirt trench, where the 6-inch wide "snowshoe" base prevents them from sinking or tipping over in the mud. Next, crews drop four parallel runs of heavy rebar straight into the 1-1/2" deep "zero-tie" plunge slots. Gravity securely locks the steel down, instantly providing perfectly parallel spacing across all four bars and a code-compliant 3-1/2" clearance, without a single piece of tie-wire required.

Drop. Lock. Pour.

Simply drop your heavy steel rebar into our massive 1-1/2" deep plunge slots. The steel gets physically trapped by natural gravity and friction, meaning no wire tying is needed. Our pre-welded chairs ensure your reinforcement stays exactly where the blueprint dictates—before, during, and after the concrete pump hits it.
