8 mm Rod Stair Runner Bracket

This corner bracket holds a stair-runner rod made from 8 mm steel, brass or wooden dowel at the tread/riser corner. It holds runners up to about 9 mm thick, because the rod's axis sits 14 mm out from both faces. Each bracket is 40 x 40 x 16 mm with a blind 8.3 mm slip-fit socket and one 4 mm clearance hole per leg for a #6 (3.5 mm) screw, one into the tread and one into the riser. The profile is symmetric, so you flip the same print over for the other end of the rod. Cut the rod to the runner width plus about 24 mm.
