Abstract
A modular system includes a post and first and second rail segments. Each of the first and second rail segments includes a tube defining a substantially hollow interior with an internal surface and an external surface and a web connected to the internal surfaces of the tube and extending across the hollow interior thereof. The web includes at least one screw boss configured for receipt of a fastener to enable engagement of the rail segment with the post.
Claims21
A modular system, comprising:
- a post;
- and
- first and second rail segments, wherein each of the first and second rail segments is a monolithic extrusion including:
- a tube defining a substantially hollow interior with an internal surface and an external surface;
- and
- a web connected to the internal surfaces of the tube and extending across the hollow interior thereof in offset relation relative to a center of the tube, the web including at least one screw boss configured for receipt of a fastener to enable engagement of the rail segment with the post.
