Caliper Studio designed, fabricated and installed this custom stair for a client in Nebraska. The top flight of the stair is composed of 1/2" thick steel plate stringers clamped around butcher block red oak treads. The outside stringer is hung with 1/2" diameter rods at 4" on center. All steel components are blackened. Special thanks to Advanced Design and Construction of Omaha for install assistance. Treads by Ethan Ames.
