The Harmony® Surface Mounted Drop Down Seal system has been specifically designed for use in pedestrian doors. The slim line style of the system incorporates a soft close feature, thereby reducing the closing forces during operation.
Harmony Drop Down Seals have been designed to provide the best acoustic performance whilst offering ease of installation on site. The drop down seals form an effective barrier to seal threshold gaps in pedestrian doorset assemblies and restrict the passage of noise, smoke and air movement.
