CISCO ENZO 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 ENZO doors can be supplied in single, double, and multi-door configurations up to 2750mm high and have been tested from both directions, guaranteeing accurate levels of protection and are backed by our 15-Year Guarantee.

High Performance

Two versions of the ENZO are available:
• Uninsulated so just a single skin with acoustics 27dB
• High-performance double skinned with higher acoustics 38dB
Enzo steel riser door sets are suitable for use in a range of different wall constructions and are fire rated up to 120 minutes, offer excellent acoustic performance, and are approved smoke sealed.

These riser doors are powder-coated in RAL 9010 fine textured paint as standard. This can serve as a final finish or can be over-painted on site to match the surrounding wall. Doors can also be finished to any specified RAL colour. The door is made of a 1.2mm thick steel skin on both sides with a 50mm insulated core.

Locking options

ENZO riser doors are fitted with a 3-point lock operated by an 8mm square drive key. All doors are fitted with a flush spring-loaded lock insert so no more issues with missing plastic bungs on site. A 65/10 euro profile cylinder (typically supplied by others) can be incorporated for greater security.
