Abstract: A novel stanchion, for insertion into and support of a tubular post of a handrail system for installation on a horizontal surface, slope or staircase, is configured with a baseplate attached to a upwardly-extending column configured with at least one pair of identical enclosed vertical slot openings located on diametrically opposite sides of the column. In a first embodiment, the column is configured with only one such pair, extending between a lower web at the bottom end region of the column and an upper web at the top end region of the column. In a second embodiment, the column is configured with eight slots arranged in two quad slot sets, each set configured with two diametrically opposed slot pairs, each pair being vertically co-linear, separated by an intermediate web. The two intermediate webs of each quad slot set are aligned at a designated height made different for each quad slot set, thus the intermediate webs of the two sets are located offset from each other vertically.

Abstract: A novel stanchion, for insertion into and support of a tubular post of a handrail system for installation on a horizontal surface, slope or staircase, is configured with a bottom flange attached to a tubular upright portion. The upright portion is bifurcated, forming a mirror-image pair of arcuate sidewalls separated at side edges by a pair of vertical slots extending upwardly from closed low ends near the flange to open ends at the top of the upright portion. The slots are sized in width to allow passage of a handrail system bottom safety member passing through a pair of drilled holes in the post at any desired spacing above the flange, with never any need for drilling the stanchion. If required to ensure against deformation of the upright portion from external forces impacting the handrail system, reinforcement can be selectably located and deployed in a manner that avoids interference with any desired location of the bottom safety member.
