Patent ID: 7874053

Claim:
A method of installing a door converter assembly in an end of a box storage container from which an end panel has been removed opposing a second end having a selectively openable door to provide dual access from opposing ends to the box storage container, comprising the steps of: (a) providing a door converter assembly comprising: a mounting frame; at least one door hingedly attached to the mounting frame; and means for selectively locking the door in a plane defined by the mounting frame for shipment and installation of the door converter assembly in an end of a box storage container from which an end panel has been removed; (b) attaching a lifting frame to the door converter assembly, the lifting frame comprising: a support frame having at least a first pair forklift pockets attached in spaced apart relation to the support frame; and a plurality of first connectors attached in spaced-apart relation to the support frame, each of the first connectors selectively moveable from a first position for engaging a portion of the door converter assembly and a second position securing the door converter assembly to the lifting frame; (c) standing the lifting frame with the attached door converter assembly in an erected position; (d) raising the lifting frame and the attached door converter assembly and inserting the door converter assembly into an open end of a box storage container; (e) rigidly connecting the mounting frame of the door converter assembly to the box storage container; and (f) detaching the lifting frame from the door converter assembly, whereby the door converter assembly with the mounting frame being rigidly connected to the box storage container, provides a selectively operable door in the end of the storage container from which the end panel was removed.
