LAS8003 si Drop Seal
A face-fixed or semi-mortised drop seal with 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. It requires no power connection. Surface mounted application suitable for upgrading existing doors.
Durable flexible elastomeric fin elements are incorporated with the housing to provide acoustic and smoke properties.
Tested for reliability, the seal completed 1,000,000 cycles without failure.
