4 x 12 Stair Hanger
This is a typical 4 x 12 metal stair hangar
providing the stringer connection to a
concrete wall. The two bolts
going into the concrete block wall provide great horizontal and vertical
support.
The stair stringer actually sits in a metal bucket which gives
it the vertical support needed as well as the two bolts attaching the
stringer to the bracket giving it the horizontal support required to
make the connection.
