Abstract: A handrail includes a support assembly for attachment to a concrete slab having an upper surface with attachment formations anchored at the upper surface. The assembly includes a handrail support component and a connector component. The connector component is attachable to the support component and an attachment formation. The support and connector components can be tightened to each other to tighten the connector component to the attachment formation for tightening the support component onto the slab. The invention extends to a handrail system including the slab, and to a method of installing handrail components on the slab.
