Outfox the ordinary with the all-new FIREFLY Fox, the smart firestopping choice for service penetrations in fire-rated walls. It’s designed to handle multiple mixed services in one unit – saving you time, labour, and complexity on-site.
Why FIREFLY Fox?
FIREFLY Fox is a multi-service penetration box crafted specifically for fire-rated separating elements. It fits neatly into pre-formed openings in fire-rated walls and walls, allowing multiple service lines – electrical, data, plumbing, and more – to pass through safely and confidently.
Flat-packed. Fox-smart. Site-ready.
Supplied flat-packed with all necessary assembly and installation fixings, FIREFLY Fox is lightweight and easy to transport and handle onsite. Its steel construction weighs just 2.3 kg with final dimensions of 300 mm wide x 125 mm high x 250 mm deep, making it practical for installers of all skill levels.
Proven fire and smoke protection
FIREFLY Fox integrates intumescent lining and foam blocks within its assembly to provide tested fire sealing around services. The foam blocks form an effective smoke seal and enable sealing to be completed from one side of the penetration only.
Faster, cleaner installation with FIREFLY Flex Foam
A standout feature is the use of FIREFLY Flex Foam, which requires application on one side only. This significantly reduces installation time and site disruption, meaning faster turnaround and less mess.
The smarter way to firestop
Incorporating FIREFLY Fox into your projects means choosing a solution that’s cunning by design and clever by default. Its thoughtful engineering reduces complexity without compromising safety or performance, ensuring the highest standards in fire protection while enhancing overall job efficiency.
