Installation Instructions

  1. Confirm that your door is a solid core door. The Sound Lock™ Bottom Seal will not work on a hollow core door.

  2. Open the door.

  3. Measure the width of the door panel from left to right. Write your measurements down.

  4. The Sound Lock™ Bottom Seal should only be cut a maximum of 2”. For example, a door that measures 31" wide should get a 32" bottom seal.

  5. The bottom seal should drop 3/8” to the floor below.

  6. Inspect your door and identify where your gaps are located. Are your gaps along the door frame itself, the door jambs, or both?

  7. Measure your door frame along the hinge side and the latch side jambs or along the door frame itself. Write down your measurements. Go back and double check them. 

  8. Measure your Gasket Seal Tape out according to the measurements of your door frame. 

  9. Peel and stick your tape along the gaps so that your solid core door is 100% sealed.

  10. Use more Gasket Seal Tape at your discretion to achieve a 100% seal.
