Important for proper use of the DoorJammer Lockdown:

• It needs to be set on a flat surface.
• No weather seals or protective strips - Many residential front doors will have a riser, flashing, weather stripping or sealing etc. that will impede the DoorJammer Lockdown or not allow it to fit properly. You will need to observe the condition of your front residential door if buying for that purpose.
• There needs to be a 3mm minimum clearance between the bottom of the door and the floor to fit the DoorJammer Lockdown.
• Designed for inswinging/inward-opening doors only.

Increase security and enjoy peace of mind with DoorJammer Lockdown - your door safety solution and door lock alternative.
