Abstract
Prefabricated handrail fittings are disclosed which contain preformed internal slots which accept simple fasteners for quickly making mitered and butt joints without hand working in the field. A plurality of interconnected slots are arranged internally along a longitudinal axis to provide fittings which are adjustable in length with only a simple transverse saw cut and which adjustably cover the entire range of angular inclination of an inclined handrail to which the fittings may be joined. A single angular fitting can be used to make either left or right turning connections between an uprising easing section and a post. A universal uprising easing is provided. Short extensions can be connected to surfaces while working from upper side without hand working.
