No more figuring out the rise and run of step/treads. Simply measure your floor to floor vertical height and then choose online the Fast-Stairs adjustable model that fits the desired height of your garage stairs. Note that our ‘’space saver’’ C models will save you considerable bottom horizontal run space if required. You can order online, by phone or email for 2 to 5 day delivery anywhere in continental North America.

Fast-Stairs offer do-it-yourself garage stairs solutions for consumers, remodelers, builders and contractors alike. There is no faster, easier or better way to build super strong and economical garage stairs. Simply bolt the stringer sections together with the slide connectors and screw the step/treads (not included) of your choice to the perforated welded steel step supports. Fast-Stairs also allow you to move and/or upgrade the finish of your garage stairs later.

All connecting fasteners with Allen key are included with the easy to ship and carry Fast-Stairs packages.

Other than a wall fastened handrail, you can choose from two simple methods for attaching railings to your garage stairs:

  1. with railing posts fastened from inside the perforated steel stringers and railing boards fastened to posts above stringers
  2. with railing posts and system attached to the top of the treads
