Description

A slimline, mortised automatic drop seal. It features 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.

Requires no power connection. Self-levelling on uneven floors; seal height can be adjusted independently of fixing screws. Can be fitted to aluminium doors by door fabricators.

Key benefits:

  • Tested for acoustic performance with BS EN ISO 10140-2: 2010.
  • Meets the smoke leakage performance requirements of BS 9999 when tested in accordance with BS 476: Pt.31.1: 1983.
  • Tested for reliability, the seal completed 1 000 000 cycles without failure.
  • Can be fitted to aluminium doors by door fabricators.
