A rail system for stairs, balconies and the like utilizes standardized components to facilitate rapid and inexpensive assembly. The rail system includes rail sections including upper and lower rails, joined by posts.

Connectors and base elements, which also facilitate ease of assembly and adjustment, are disclosed.
