A drop-down seal is a great way to help soundproof your door against noise entering through the gap underneath the door. This fire-rated door sweep is made for keeping airborne sound contained by minimizing the gap under the door in your home, office or recording studio. This under-door seal is recess mounted and automatically drops down as much as 3/4” to seal the under-the-door gap. Dimensions are 36” long, 29/32” wide and 2-1/16” high. The length can be trimmed up to 2” for a perfect fit.
This mortised wood adjustable door bottom seal is not designed to seal directly on a carpeted surface but should seal on a solid surface.
