• Approvals in timber walls and floors 
• Increased cable sizes in 75mm drywall approvals 

Protecta FR Service Transit is designed to maintain the fire resistance of walls and floors breached by continuous cables and plastic pipes. 

The service transit is made up of a circular, high temperature plastic tube which contains a graphite-based intumescent lining material that expands upon heating to seal spaces or voids around cables and pipes, thus preventing the passage of flames, smoke and gases.
