Abstract
A handrail assembly that can be installed on any wall. The assembly has a handrail and a bracket. The bracket can be twist-locked inside the handrail at any point in the handrail because the handrail has a continuous T-shaped channel at the bottom. The T-shaped channel's bottom portion is narrower than the upper portion. The bracket has a head that is as wide as the T-shaped channel's bottom portion and as long as the T-shaped channel's upper portion. The head has one curved corner to facilitate turning and teeth to bite into the upper portion of the channel's wall. The head is lifted through the bottom portion into the upper portion of the channel, the bracket is rotated a quarter turn, and the bracket becomes immobilized. The head of the bracket acts as a cam. Union joints can join multiple lengths of handrails.
