Abstract: A wood-form splice stake includes an elongated stake member having a lower end adapted to be driven into the ground. A pair of flat flanges extend laterally outwardly in opposite directions from the upper end of the stake member for securement to respective adjacent ends of aligned concrete form boards for maintaining them in alignment and securing them against relative vertical movement. The stakes are preferably formed so as to be stackable in nested relation. A stake carrier includes an elongated base having an upstanding post insertable through aligned pull holes in the stacked stake members. The other ends of the stake members are confined between upstanding legs on the base plate to prevent pivotal movement about the post. A lock device is operatively associated with the post for releasably locking the stakes against removal from the post.Metal-to-wood form adapters are provided for aligning and supporting wood form boards relative to conventional metal forms.
