  • Open door security device
    Patent number: 6520551
    Abstract: A security device for use in securely fixing the entry path of an enclosure in a predetermined semi-open position includes a first member removably mountable to a structure associated with the entry path to an enclosure and a second member removably mountable to a different structure associated with the entry path to an enclosure and a spacer extending between said first and second members. The security device acts to fix the structures associated with the entry path in a predetermined, spaced position with respect to one another such that the entry path is semi-open to allow access into the enclosure for equipment but which prevents a person from gaining entrance to the enclosure through the entry path.
