How it works

Square profile locks the form

Set the stake beside the board and drive the point into the ground. The square cross-section resists rotation and maintains board alignment during the pour.

Round Stakes
Choose round stakes for general board holding: the circular section drives cleanly beside wood or plywood boards.
Flat Stakes / “C” Mouth Stakes
Choose flat stakes when you want a flat bearing surface against the board and good ground resistance to turning.
Square Stakes This page

Rebar Stakes
Choose rebar stakes when you want the ribbed surface and tensile strength of reinforcing bar for driven hold-down work.
