🔍 Product Description

Acoustic Door Drop Seals are designed for the gap between the door bottom and floor. They provide an excellent barrier to airborne sound, ensuring the acoustic attenuation provided by a door set. This heavy-duty, concealed automatic door bottom seal is mortised into the bottom edge of single action doors.

It operates automatically by a spring-loaded mechanism which lifts the seal clear of the floor as soon as the door is opened. The sealing gap ranges from 3mm to 13mm.
