A standard door can have as much as one square foot of airspace around the edges. Imagine if you had a 12" x 12" hole in your wall! It wouldn't block very much noise, would it? The Sound Lock™ Door Seal Kit is the durable and effective solution to turn a solid-core door into a soundproof door.

  • Each kit includes 3 adjustable jamb seals and an adjustable bottom seal

Installation Instructions

  • Sound Lock™ Door Seal kits should not be used on a hollow-core doors.
  • The included screws can be used on wood or metal door frames. For metal door frames, confirm there's a decent gauge of metal and drill a pilot hole. A finer thread screw may be needed for very low gauge of metal.
  • For carpet applications, a flat smooth threshold (not included) should be used.
  • Recommended 1-1/2" of flat space on the door jambs to install the jamb seals.
  • The bottom seal should drop 3/8” to the floor below.

How to Measure Your Door

  1. Open the door.
  2. Measure the distance from the floor to the top of the door frame. Write it down.
  3. Measure the width of the door frame across the top frame. Write it down.
  4. Double check your measurements to ensure you get the correct sized kit. The bottom seal should only be cut a maximum of 2".
