Harmony Acoustic European drop down door seal, fitted to allow acoustic sealing and minimise closing force of door sets. Inserted into the door for an even and controlled drop across the threshold. For use with timber doors.
Harmony drop down seals have been designed and tested to BS EN ISO 10140-2:2010 successfully providing the best acoustic performance whilst offering ease of installation on site.
