The trapdoor is also airtight to EN 14975 (DN 4570) Class 4 and the hatchbox has a rubber seal all the way around. White coated mitre cut strips are provided ready to be pinned on the underside of the hatchbox.
Supreme Options
Vertical
The Supreme stairway can also be used for access in vertical walls. The maximum operating height for the Supreme with vertical access is 3390 mm.
Electrically Operated
The electrically operated stairway runs on 24V DC and is fully supplied with wiring, stand-by battery, transformer and operating switch. It is also possible to fit a further switch thereby allowing operation from above.
Weatherproof Roof Hatch
A fully weatherproof hatch suitable for roof access is available.
Fire Resistant Casings
We can offer the Supreme with a choice of fire resistant casings:
a) the wooden hatchbox and trapdoor coated with pyroex to give a 30 minute fire resistance or
b) the steel hatchbox and trapdoor with either a 30 or 90 minute fire resistance.
Suspended Ceiling
The Supreme is suitable for use with suspended ceilings. When installing a deep hatchbox within a void e.g. an area between a suspended ceiling and the main ceiling, then we would recommend the use of bracing from the main ceiling to the outside of the hatchbox to add stability.
