Designed for fail-safe DIY condo stair building and installation

Fast-Stairs provide a unique, quick and easy way to build long lasting, free-standing 2½ to 13 ft high condo stairs. No stair stringer calculator required. Simply measure your floor to floor vertical height and then choose online the Fast-Stairs adjustable model that fits the desired height of your condo stairs. Make sure you have the necessary bottom floor horizontal run and that your top opening is large enough (usually 75% of the horizontal run measurement) for an 80'' head clearance. Fast-Stairs also offers steeper space saving (8¼" stair riser height) condo stair models.

Fast-Stairs offer do-it-yourself permanent condo stairs solutions for consumers, re-modelers, builders and contractors alike. There is no faster, easier or better way to build super strong and economical condo 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 condo stairs later.

Order online, by phone or email for 2 to 5 day delivery anywhere in the continental USA and Canada. All zinc-plated connecting fasteners with Allen key are included with the easy to ship and carry Fast-Stairs packages.
