Kilargo IS3100si Weather Resistant Door Bottom Seal

Door Bottom Seal used to close gaps around door frames (the jambs and the header). Sound, light, draught, moisture, fire, and smoke can all be significantly reduced by closing the gaps along the door frame.

Door Bottom Seal Function - the seal has a spring loaded mechanism which lifts the seal clear of the floor, in a parallel motion, as soon as the door is opened. Pressure against the door jamb on the adjustable brass strike button operates the seal automatically.
