DION Riser Doorsets

Designed and fire tested specifically for use in riser shafts running through buildings. CISCO fire tested DION Riser Doors provide protection to riser openings preventing fire escaping from the riser shafts and spreading throughout multistorey buildings. This is possibly the most important access door in the building for preventing the spread of fire to other floors. Doors up to 2747mm high have been tested guaranteeing accurate levels of protection all backed by our 15 Year Guarantee.

By taking advantage of our unique spring-loaded pivot hinging system, installation time 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 full 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. These high-performance interlocking door sets are almost a 100mm in thickness and boast high acoustic ratings, 2 hour+ fire rating and are approved smoke sealed.
