Application

Suitable use for:

  • Single swing, single and double leaf doors.
  • Can be used on either right or left handed doors.
  • Fire rated steel doorsets.
  • Wheeled traffic.

Description

A heavy duty, mortised automatic drop seal, featuring a high efficiency mechanism, which lifts the seal clear of the floor as soon as the door is opened by a few millimetres; resulting in lower door operating forces.


Features and benefits:

  • Requires no power connection.
  • Self-levelling on uneven floors; seal height can be adjusted independently of fixing screws.
  • Meets smoke requirement: BS 9999:2017.
  • Protects against smoke, draught, light and insects.
