Key-Link American Series Aluminum Railing Section Detail Drawing

This detailed section drawing illustrates the Key-Link American Series aluminum railing system with customizable configuration options. The railing spans either 72″ or 96″ between posts, with post height options of 38″ or 44″. The top rail height measures 36″ or 42″ depending on post selection, featuring the distinctive American Top Rail profile. Square balusters are shown as the standard option, though alternatives include twisted, hammered, bowed, hammered bowed, round, indented, decorative, horizontal cable, and vertical cable designs. Posts come with mounting plates in three size options: 2-1/2″, 3-1/4″, or 4″ square, all compatible with either height configuration. The drawing includes a detailed cross-section (A-A at 1:3 scale) showing the internal post structure and connection details. Post caps are available in ball or flat styles (not illustrated), while post trim options conceal mounting hardware. The system’s modular design allows for flexible installation configurations while maintaining structural integrity for residential and light commercial applications.
