Zero-Tie Rebar Support. Designed for 3 Parallel Bars.
3-Bar Footing Chair
Maximize Trench Efficiency with the 3-Bar Footing Chair
The Synchro 3-Bar Footing Chair is purpose-built for heavy-duty, deep foundation projects requiring three runs of steel, such as large-scale barn foundations, commercial grade beams, and heavy perimeter frost walls. Specifically engineered for raw, uneven dirt trenches, this chair completely replaces the need to place and measure three separate, flimsy single-wire supports. With factory pre-welded spacing that holds three parallel rebar rods at the exact specified intervals, your crew can put their tape measures away and cut foundation prep time 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.

3 BAR FOOTING CHAIR PLACEMENT & USAGE
Designed for deep trenches and heavy grade beams, the Synchro 3-Bar Footing Chair offers a foolproof "drop-and-pour" setup. Workers place the pre-welded chairs directly into the excavated dirt trench, where the massive 6-inch-wide "snowshoe" base prevents them from sinking or tipping in the mud. Next, crews drop three parallel runs of heavy rebar straight into the 1-1/2" deep "zero-tie" plunge slots. Gravity securely traps the steel, instantly providing perfectly parallel spacing and a code-compliant 3-1/2" clearance without ever needing to touch a roll of tie-wire.
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.
Frequently Asked Questions
Where is this chair used?
Down inside excavated dirt trenches and deep mud.
Do I need to tie the 3 pieces of rebar?
No, the three 1.5-inch deep "Zero-Tie" lock slots hold all three bars securely through gravity and friction.
What is the overall height of the chair?
It provides a 3-1/2 inch clearance height from the dirt.
What is the spacing between the rebar rods?
Exactly 8 inches.
Will it tip over in the mud?
No, the 6-inch wide "Snowshoe" A-frame is specifically built to prevent mud-tipping.
Is the steel certified?
Yes, we use traceable Canadian steel and can provide full Mill Test Reports (MTR) for commercial compliance.
