摘要： A handrail assembly having seamless joints. The exposed components of the handrail are lengths of thick-walled plastic pipe and selected components have a metallic liner. The plastic pipes are joined to one another at any desired angle with the use of an alignment stud. The alignment stud has one end formed as a saddle at the desired angle to its axis and is attached to the one component by a threaded fastener passing through the stud. The hollow cylindrical saddle of the stud bears against the outside of the plastic pipe of the one component and is held in tight engagement against the pipe by the threaded fastener. The plastic pipe of the other component is likewise formed with a hollow cylindrical saddle adapted to mate with the outside surface of the first component and is telescopically engaged over the fastened stud and is anchored in place by a set screw passing through the plastic pipe into the stud. The head of the set screw is concealed by a plug. The exposed surface of the plug and the surrounding surface of the plastic pipe are sanded and polished so as to conceal the plug.
