A portable adjustable stair railing includes a plurality of telescopically adjustable balusters having structural attachments at the bottom of each, such as, for example, adhesives, suction cups, or removable fasteners, such as bolts. The height adjustment for each baluster is set by spring-biased buttons and cooperating apertures located on the two sleeved portions of the baluster. The top balustrade receiving end of each of the balusters includes a collar-like receiver and a set screw to hold the balustrade in the desired position. This balustrade collar further includes a pitch or angle adjustment for allowing pitch lines, or runs, on various staircases.
