Ideal For

1. Air-Conditioned Rooms: Preventing cold air from escaping by ensuring the door closes behind you, helping to reduce electricity bills.
2. Home Offices: Maintaining privacy and reducing noise without having to manually close the door every time someone enters or exits.

Installation Tip: For the strongest hold, clean the surface of the wall and door thoroughly with alcohol before applying the adhesive. Once attached, wait 24 hours before letting the device pull the door to allow the adhesive to fully cure and reach its maximum strength!
