Abstract: The present invention relates to a modular railing system for use as a handrail or bumper rail that has a substantially continuous and smooth exterior surface that is easily cleaned and helps prevent the collection and accumulation of surface contaminants. The system is comprised of multiple modular sections which can be secured together using internal connectors which eliminates the need for any exposed mechanical fasteners. The sections can be made straight or curved to allow the system to be constructed in various configurations. Support fixtures are also provided which can be used to connect the system to the wall.
