ABSTRACT:
A handrail support assembly has a tee member fitting into a support baluster above each tread of a spiral staircase. The upper cross member of the tee member fits into channels formed under the handrail. The channels are formed by return bending the sides of the rail. The tee member will support and position a spiral rail while being rotatable somewhat in the channels of the rail so that a predrilled nonprecision hole in the lower portion of the tee member may be aligned with a hole in the baluster for attachment with a screw. Precision components are avoided.
