NOR 810S
The NOR 810S is a smaller alternative to the NOR 810. This BS 476: Part 31:1 smoke seal compliant automatic drop down seal has a light weight mechanism which is self levelling when activated. This seal has passed a 100,000 cycle test with ease.
The NOR810S acoustic door seal is adjustable to suit the gap size needed and will not only act as an acoustic barrier but also help keep out drafts and keep in energy!
