The Staybox system is prebent rebar and a formed metal box that creates a single “pull out” bar assembly.
The assembly is used as a keyway and lap splice between concrete construction joints, including slab, deck, wall, beam and column intersections. The two-piece metal box is designed so the back plate remains in the concrete, while the front plate can be removed for access to the prebent rebar inside. The box itself and both ends are sealed to prevent concrete from seeping into the assembly.
