Harmony Acoustic surface-mounted Drop Down Door 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.
Stocked in 2 sizes, 935 and 1035mm, the Harmony acoustic drop-down door seal forms an effective barrier to seal threshold gaps in doorset assemblies, restricting the passage of noise, smoke, and air movement.
When activated, the drop-down element seals gaps of up to 14mm*
The unique patented design plunger (activator) is manufactured from high-performance glass-filled nylon and can be manually fully adjusted in situ.
This brilliant ‘click-it’ fit system negates the need for springs and can be installed without the need for mechanical tools, making assembly and installation quick and efficient.
Manufactured from durable glass-filled nylon, the assembly of the plunger means it can be easily replaced if damaged, negating the need to replace the complete unit.
- Cycle tested to 200,000 cycles, showing no loss in sealing performance.
