Application

Suitable for new and retro fit projects, providing smoke containment along with acoustic properties as part of an acoustic sealing system. The automatic door bottom lifts the seal clear of the floor when the door is opened, providing a lower door operating force.


The drop down door seal can be used in combination with threshold plates TL, TM, TN from the Sealmaster Thunder range, to provide a more effective seal and allow for a larger under door gap.

Description

Sealmaster automatic DropSeal has been engineered to fill the gap between the door bottom and the floor or threshold plate (maximum gap of 12 mm). The seal is operated automatically by pressure against the door jamb on its adjustable plunger. The spring loaded mechanism ensures a self-levelling sealing along the entire door bottom length. The mechanism retracts into the aluminium case when the door is opened.


The seal is available in a range of sizes from 535–1135 mm, each of which can be cut down by up to 100 mm to suit the door width.


The product is also supplied with fixings including stainless steel clips, frame protector and screws. Quick and easy installation with hidden fixings.


It has been tested to BS EN 1634-1, BS EN 1363-1 and BS 476-22. Test data available on request. It has been durability tested to over 1,000,000 cycles. Test evidence on request. The case and carrier is aluminium with an extractable internal mechanism with steel leaf springs, the seal is in self extinguishing silicone.
