CISCO DION steel riser doors are designed and fire tested specifically for use in riser shafts running through buildings. They provide protection to riser openings, preventing fire from escaping from the riser shafts and spreading throughout multistorey buildings.

Guaranteed Protection
These steel riser doors are possibly the most important access doors in the building for preventing the spread of fire to other floors. The DION doors are up to 2747mm high and have been tested, guaranteeing accurate levels of protection and are backed by our 15-Year Guarantee.
Easy Installation
By taking advantage of CISCO’s unique spring-loaded pivot hinging system, the installation time of the DION riser doors is reduced, offering significant savings in fitting costs with the advantage of being able to simply remove the doors giving the benefit of a full clear opening when required.
An improved 5-point locking system has been engineered to offer complete security to restricted M & E services, whilst seamlessly blending with the surrounding walls. For a truly concealed look, specify with the spring-loaded invisible keyhole system.
High Performance
The DION high-performance interlocking steel riser door sets are almost 100 mm in thickness and boast high acoustic ratings, 2 hour+ fire rating and are approved smoke sealed.
These riser doors are powder-coated in white RAL 9010 as standard with the ability to be finished in any RAL colour or primed for on-site painting. The door is made of steel skin on both sides with an insulated strengthened door core.
