Key specifications

  • Automatic Door Bottom — the seal closes the gap between the door and the floor each time it shuts, with no dragging across the floor
  • Drops on closing and lifts on opening — the seal sets itself, so nobody has to remember to do it
  • Neoprene Gasket seal — a solid rubber gasket that squashes flat against the floor and springs back every time
  • Blocks sound, light, air, smoke, fire, and insects — one seal handles what a door gap lets through
  • For soundproofing recording studios, performance halls, hotel rooms, offices

An automatic door bottom, surface mounted, with a neoprene rubber bulb in an aluminum housing. Heavy Duty. A plunger at the hinge end pushes the seal down onto the floor as the door shuts, and lets it lift again as the door opens.

Why this rather than a door sweep

A sweep drags along the floor every time the door moves. An automatic door bottom only touches the floor when the door is closed, so it seals just as tightly without wearing the floor, catching on carpet, or making the door harder to push. On a door that opens hundreds of times a day, or over a finished floor you care about, that is the whole argument.

What to check before you order

The gap under your door. This unit drops 1". Measure the gap at its widest point — if the floor is uneven, measure where the gap is largest.

The mounting. It surface mounts to the face of the door bottom, so no routing is needed — the retrofit option.

Cut to length from the sizes listed. Fire rated — the fire label is available on request.

This Automatic Door Bottom seals your door sill from unwanted sound, light, drafts, bugs, smoke, fire and more. Secure and soundproof recording studios, performance halls, offices, and hotel rooms.

Just close the door and the tough neoprene seal automatically drops to the floor or saddle in a diagonal movement, creating a tight seal even when floors are not perfectly level. Retracts when the door opens.

  • Includes 1 pair of end caps. Comes with standard screws (#8 x 1-1⁄2″ SMS self-drilling screws)
