Application

Suitable use for single swing doors. For use on both right and left handed doors. Can be used with any perimeter seal.

Description

A slimline face-fixed automatic drop seal.


Features and benefits:

  • 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.
  • Surface mounted application suitable for upgrading existing doors. Requires no power connection.
  • Self-levelling on uneven floors; seal height can be adjusted independently of fixing screws.
  • Durable flexible elastomeric fin elements are incorporated with the housing to provide acoustic and smoke properties.
  • Tested for acoustic performance with BS EN ISO 10140-2: 2010.
  • Meets the smoke leakage performance requirements of BS 9999 and is used for sealing the threshold of door assemblies against leakage of ambient temperature smoke, as defined in BS 476: Part 31.1: 1983.
  • Suitable for use on timber fire doors for up to 60 minutes under conditions of BS 476: Pt.20/22: 1987 and BS EN 1634-1: 2014 (when face-fixed).
  • Tested for reliability, the seal completedcycles without failure.
  • Minimum/ maximum gap size: 1 mm/ 13 mm.
  • Acoustic performance: Weighted Sound Reduction Index (Rw): 31 dB.
