Designed and fire tested specifically for use in riser shafts running through larger buildings. The Access Panel Company fire rated Christo Riser Doors provide protection to riser openings preventing fire escaping from the riser shafts and spreading throughout multi-storey buildings. This is possibly the most important access door in the building for preventing the spread of fire to other floors. Doors up to 2866mm high have been tested guaranteeing accurate levels of protection.

The SLIK Invisible Keyhole System
Our patented SLIK ‘Spring Loaded Invisible Keyhole’ system seamlessly blends the panel surface across the face of the keyhole making it almost invisible.
The keyhole cover is pushed aside as the key is inserted into the lock and springs back into place when the key is withdrawn.
The SLIK removes the need for keyhole caps that can go missing or become grubby over time.

Frame Options
With 4 frame types, we can accommodate any wall finish. The Concealed beaded frame (below right), is the most popular & used where the wall has yet to be finished. For finished walls, the Picture frame option is available or specify no flange or delete the flange to the threshold only. Ask for a primer paint finish and site emulsion so the door blends into the wall. All options are fully fire tested.
