MECHANICAL LOCKING MECHANISM FOR HOLLOW METAL DOORS
Implementations of a stiffener joint are provided. In some implementations, the stiffener joint comprises a pair of interlocking beams having a mechanical locking mechanism requiring no welding. In some implementations, the pair of interlocking beams comprises a first beam comprising a plurality of tabs extending from the first beam and forming a hook and a second beam comprising a plurality of opening. The tabs of the first beam extend through the respective openings of the second beam and a portion of the second beam is positioned in the hook formed by the tab of the first beam thereby interlocking the beams. In some implementations, the stiffener joints may be used inside hollow doors.
