The Super Simplex is Precision's commercial-grade aluminum folding stairway. It is the most structurally superior product of its kind on the market today. Its primary use is as an attic stairway, but when fitted with a Precision roof hatch can be used for roof access. The manually operated Super Simplex is now available in 2 different models: The S1000 series which are designed for commercial installations, and the S2000 series which meet all the criteria for residential use as designated by ANSI A14.9 Safety Requirements for Disappearing Attic Stairways. Compare these features to other attic stairs:
- Can be used for ceiling heights up to 12' 0" in commercial applications – S1000 (and up to 13' 6" for residential use – S2000)
- A test weight of 500 lbs.
- Individual tread test weights of 1000 lbs.
- No shear of rivets when tested at 2000 lbs.
- 11 gauge steel frame
- A 5-3/16" tread depth.
- Availability of optional 2-HOUR FIRE-RATING
- Meets or exceeds ANSI A14.9
The Super Simplex is the only pull-down stairway available with a frame complete with built-in treads custom fabricated to the exact distance from ceiling-to-floor-above, thereby accommodating dropped ceilings.
For secure access to rooftop equipment, Precision offers a package unit consisting of a folding stairway, a custom frame to fit distance from ceiling to roof and a custom roof hatch factory-mounted to the top of the frame. This entire unit can then be dropped in from above, secured and flashed in for safe, comfortable roof access.
The Super Simplex allows attic space to be reclaimed for storage purposes without the need for a permanent stairway. Many national companies are already using the Super Simplex to maximize use of floor space. Some typical applications are: airport control towers, banks, better residences, bottling plants, churches, drug stores, government buildings, hospitals, laboratories, libraries, museums, restaurants, schools and retail stores. While this pull-down stair was originally designed for commercial installations, it is also available in sizes to fit standard residential truss spacing and ceiling heights of up to 13' 6".
