Product Description

BOSS Fire® Transit Box – Multi Service Cable and Pipe Transit

“The Game Changer”. Offering the simplest and most effective fire stopping method available.

The latest generation of BOSS Fire® Transit Box provides 2 hours of fire protection for clusters of multi-service cables and pipes in one integrated box.

Ideal for apartments and commercial applications, this latest model BOSS Fire® Transit Box  is simple to install and offers an innovative method of fire stopping with a higher performance on more services than ever before.

Due to our advanced intumescent “BOSS FireMastic-HPE” sealant, the Australian-made BOSS Fire® Transit Box guarantees a fast-acting reaction to fire, expanding internally within the box and closing rapidly around the penetrating services.


BOSS Fire® Transit Box offers industry-leading 2 hours of fire resistance

The BOSS Fire® Transit Box has been successfully tested to stop the transfer of fire and smoke through the wall and insulate the services from heat transfer for over 2 hours.

With a Fire Resistance Level of -/120/120, it offers a far superior performance to any other product available on the Australian market.

Saves time & money

The BOSS Fire® Transit Box is simple & cost effective to install. It has been developed with BOSS’s own innovative smoke resistant and flame-proof brush seals on the face of the box, which quickly seal around penetrating services.

As there is no cutting or fitting required, installing services through the BOSS Fire® Transit Box literally takes seconds. It eliminates any concerns about the ability of subcontractors to provide certifiable firestopping systems.

“Reduce Installation labour by up to 90%”

Designed for complex fire rating applications

The BOSS Fire® Transit Box has been designed in conjunction with some of Australia’s leading construction design partners. It offers major benefits to the typical apartment project or any application requiring multiple services to be fire rated in confined spaces.

It is suitable for:

  • Apartment entry walls  and above doorways in high-rise residential apartment blocks
  • Computer rooms and data centres
  • Corridors and tunnels where services pass through multiple fire rated walls
  • Riser shaft walls to common areas
  • Industrial applications with “multi-service” requirements
  • Office tower passive firestopping and fire rating.
  • Use in concrete floor slabs

“We tried the BOSS Fire® Transit Box in our new apartment project West End, Brisbane because it was recommended to us. To be honest I didn’t realise how much it was going to save us, the installation time is extremely fast and our total fire stopping labour time has been slashed. It’s the simplest, most effective fire stopping method available.” – Peter Haines BPM Group
