NOR810 Drop Seal

Specifically designed and manufactured by Norsound in Germany, quality and attention to detail have been at the forefront of every design decision. Some clever design changes make this drop seal our most advanced to date.

The robust internal mechanism allows for parallel actuation, whilst a complete overhaul to the seal profile provides for the most durable seal yet.

The actuator has been manufactured with Teflon, giving it a smooth surface that eradicates damage to door frames. Added to this, it can now be completely removed from the product when necessary.

The option to adjust the actuator by hand means that no tools are required for adjustment and seals can be deactivated when on site.
