Fire doors


Korok (Speedwall) Jamb (Steel)    


  1. The opening in the Korok wall must have the Korok C track fitted, to give secure fixing of the steel door frame.
  2. For fire rating compliance, the opening in the Korok wall must be lined with 12mm thick Prometect 100. The paperwork received with this doorset will state the trim size required. The trim size stated is the opening size required BEFORE lining the opening with the 12mm thick Prometect 100.
  3. Ensure that the correct door is to be installed in the opening.
  4. Check for damage caused during delivery, or storage on site. Notify the contractor immediately if damage is present
  5. Ensure that any hardware ordered, and the Installers Declaration has been supplied.
