LAS8001 si HSS Drop Seal

This fully mortised aluminium automatic drop seal features a silicone rubber gasket with intumsecent core and internal fins. It is used to close the gap under single swing doors to maintain their acoustic, smoke or energy efficiency performance. The seal incorporates a high efficiency spring loaded mechanism that extends the seal as the door swings shut and automatically retracts it as the door is opened by just a few centimetres.
