Drop Down Threshold Seal 764mm-914mm
This drop down door seal is BS EN 1634-1: 2014 fire tested, and smoke tested to BS EN 1634-3: 2001. It is also acoustic tested up to 44DB to BS EN ISO 10140-2: 2010.
This drop down door seal has a lightweight mechanism that is self levelling when activated. The ultra soft TPE bubble seal is mounted in a satin anodised holder that is released when the door is closed dropping on to the threshold and sealing the gap. When the door is opened the spring loaded mechanism retracts the holder up in to the bottom of the door.
Installation is simple, rebate a channel in the bottom of the door 12mm wide to a depth of 20mm, cut the door seal to length and insert in to the rebate, a strike plate is attached to the door frame, and adjustment is made with the grub-screw.
This threshold seal is suitable for gaps between 3 and 13mm. Drop down adjustment length is achieved by pulling out the actuator button and turning; anti-clockwise to lower, and clockwise to shorten the drop.
