NORSEAL NOR815 RETROFIT DROP DOWN SEAL 915MM

The Norsound NOR815 is a surface-mounted automatic drop seal designed for retrofit installation to the bottom of doors where draught control, smoke sealing, and acoustic performance are required. When the door closes, the self-levelling mechanism automatically lowers the seal to close the gap beneath the door, then retracts when the door is opened. Manufactured from durable aluminium with a PVC gasket, the NOR815 offers excellent performance while requiring no routing or modification of the door. Its compact profile and generous 17mm gap coverage make it ideal for both residential and light commercial applications.
