Installation Instructions
Installation Instructions
- Sound Lockā¢ 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 3/8ā to the floor below.
- The astragal seal should be installed between both doors.

How to Measure Your Doors
- Open the doors.
- Measure the distance from the floor to the top of the door frame. Write it down.
- Measure the width of the door frame across the top frame over to the end of the door panel. Write it down.
- Double check your measurements to ensure you get the correct sized kit. The bottom seal should only be cut a maximum of 2".
