Acoustic / Automatic Drop Door Bottom Seals

A simple yet functional sealing mechanism that is pressed automatically against the floor by a hinge-side plunge which contacts the jamb as the door closes. The seal forms a tight secure bond against the floor when the door closed and retracts automatically as the door opens. It will help to prevent hot/cold draughts, acoustic, energy and smoke infiltration.
