PRODUCT DESCRIPTION

Choose this 426 mm ExiSound Concealex A8100 Superior when a recessed automatic drop seal is specified for the bottom of a suitable door. Its satin anodised aluminium profile houses a self-levelling, sound-insulating TPE seal. Confirm the door construction, routing space and required finished length before ordering.

426 mm seal specifications

  • Stock code: EXT102B
  • Nominal length: 426 mm

  • Maximum drop: 17 mm

Check the fitting method

The fitting instructions call for a 14 mm wide × 35 mm deep slot in the door bottom, with additional preparation for the endplates. Follow the instructions for the endplates and plunger adjustment. Compare the 330 mm recessed version if that nominal length suits your project. Where routing is unsuitable, see the face-fix Concealex version. Browse other door seals and draught-proofing products.

Fire, smoke and acoustic evidence

The A8100 Superior range brochure reports fire testing for 30 and 60 minutes to BS EN 1634-1:2014 and acoustic testing up to 44 dB to BS EN ISO 10140-2:2010. CERTIFIRE CF5785 addresses smoke-sealing use subject to its specific door-assembly and installation conditions. These are product test details, not a guarantee of the performance or rating of an installed door assembly.
