Top-Mount Stairs



Mount these stairs to an elevated landing for easy access. They have adjustable mounting brackets to accommodate slight differences in landing heights. Steps are perforated to provide slip resistance that’s easy on your shoes.
Stairs that meet IBC standards are used in commercial buildings that may be accessed by the general public. With larger step dimensions and a shallower angle than OSHA stairs, they are easier to climb. In addition, the vertical space between steps is covered by risers to prevent debris from falling through. Replacement risers are sold separately.
Note: Stairs meet OSHA and Cal/OSHA, or IBC dimensional standards. Users are responsible for checking local, state, and federal codes, including OSHA or IBC, for safe installation and operating practices.
