Triad's Smart Stair Router (SSR) was designed to provide years of rugged service with the accuracy of Computer Numerical Control.  An operator can load 2 x 10 or 2 x 12 stringers, enter menu driven parameters with a state of the art touch screen monitor, and press "Run"!  Triad's SSR does the rest!  Two heavy duty routers will cut the top or bottom stringer only, or both stringers simultaneously with the specified profile.  It will automatically index the material the proper distance, the appropriate number of times, and do it again!  Triad's SSR can accommodate standard stair profiles, no-riser profiles, and split stringer configurations, open stringer. User configured "Hard" or "Soft" wood selections automatically adjust the router feed rate to maximize performance. 

Over the course of the last several years, 
Triad has put a significant amount of research and development into upgrading the technology of our SSR. New pro
gramming now allows for 520  routing options-- the original automated version allowed eight. We have also added the capability to cut an Open Stringer  with this machine. The SSR can accommodate a Multi-Flight option that allows an operator to program more than one flight of stairs into the same stringer, and a Multi-Order feature to back up several orders at a time until the machine is ready.
