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. Installation of the NOR820 drop seal provides smoke and acoustic performance without the removal of timber from the door. Fitting of the seal is not detrimental to the doors performance for fire resistance.

Door manufacturers such as Falcon Strebord, Halspan, Flamebreak etc advise: Surface mounted automatic drop seals may be used where the fitting of these does not require the removal of any core material.

Recommended to be used in conjunction with NOR630 Aluminium Threshold.
