Norsound NOR820 Retro Fit Door Bottom Drop Seal - Various Widths
Application
This product is designed to be fitted to the bottom edge of acoustic timber or metal doorsets to close the gap to the floor and create and airtight seal. This is a retro-fit product and is fitted by being screwed to the bottom edge of the door.
