Designed and fire tested specifically for use in riser shafts running through larger buildings. The Access Panel Company fire tested Christo Riser Doors provide protection to riser openings preventing fire escaping from the riser shafts and spreading throughout multistorey buildings.

For a truely concealed look specify with the new patented SLIK+ lock concealment system from The Access Panel Company.
