Are prices indicated for the two stringers?

2x10s or 1″ hardwood treads: up to 36 inches wide
2x12s or 1¼” hardwood treads: up to 48 inches wide


What about raillings?

There are two simple methods for attaching railings to your stairs:

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

How do I determine which Fast-Stairs model I need for my stair project?

Fast-Stairs provide a unique, quick and easy way to build long lasting, free-standing 2½ to 13 ft high stairs. No stair stringer calculator required. No more figuring out the rise and run of steps. Simply measure your floor to floor vertical height and then choose the Fast-Stairs adjustable model that fits the desired height of your stairs. Make sure you have the necessary bottom floor horizontal run and that your top floor opening is large enough (usually 70% of the horizontal run measurement) for an 80″ head clearance.
