KK72 Stair Tread Support


KK72 is a stair tread support suitable for most types of stair tread, including timber, open steel and checker plate. Fixing of the treads is by two bolt holes in each fitting. Ø indicates diameter of fixing holes. (Special Order Only) If KK72 fittings are to be used for a permanent application or subjected to high loads, the stair tread support pipe which is located at its ends with a single set screw, should be drilled and pinned to avoid rotational slip.
