Your Personal Guardian
This new security device works on all doors with carpeted flooring. Simply place this device on the floor against the door (to prevent it from being opened at all) or about 2 inches near the door opening (to allow the door to be opened slightly but to still be secured). This remarkable new invention replaces old fashioned door chains that have to be installed but that can be ripped out and broken with little pressure. The Portable Deadbolt can withstand 100's of pounds of pressure, unlike the impracticle and out date chain lock systems.
