Sound Lock™ Double Door Seal Kits

Soundproof double doors with the Sound Lock™ Double Door Seal Kit. Double doors have even more air gaps than single doors, further increasing their need for a sealing solution. Whether these doors are in an office, school, or other, there's no better way to keep unwanted noise out of a room with double doors.

• Soundproofs any solid core double doors by sealing off the open air gaps
• The bottom seals and jamb seals are adjustable to allow for an airtight fit on any standard double door
• Adds up to 20 STC points (MAX: STC 51)

Installation Instructions

• Sound Lock™ Double Door Seal kits should not be used on 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.
• The astragal seal should be installed between both doors.

How to Measure Your Doors

1. Open the doors.
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 over to the end of the door panel. 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".
