Does the Orginal DoorJammer Lockdown come with an extension foot?
No, Lockdown is the taller model so it doesn't require extensions.
Do I need to use the provided spacers?
No, the spacers can improve performance but the Original DoorJammer was designed and tested without them.
If my door is fitted with a draft excluder or a rubber kickstrip, will the Original DoorJammer still
work?
Yes, as long as the strip does not prevent DoorJammer fitting under the door. Crushing or damage to the strip could occur, however.

Yes, DoorJammer works just as well!

Will the Original DoorJammer prevent Fire or Police services getting in during an emergency?
