Increased strength dogging mechanism

A dogging mechanism operable by a handle for releasably securing a door on each side of the door to a structure, the dogging mechanism comprising:

• a plurality of dog keepers having a ramp portion and a seating portion with at least one dog keeper for attachment to each side of the door;
• a plurality of guides;
• a dog rotatably mounted to each guide for movement between unlocked and locked positions;
• a plurality of mounting bolts, each mounting bolt extending through each guide and each dog for securing each guide and each dog to the structure;
• a roller rotatably connected to each dog and disposed to engage a cooperatively associated dog keeper;
• and
• a drive assembly for movement by the handle between open and closed positions, the drive assembly including a plurality of rods connected to the guides with at least one rod slidably mounted for attachment to each side of the door so that when the drive assembly is moved between open and closed positions the rods and the guides are translated causing the dogs to rotate between the unlocked position, in which the roller of each dog is disengaged from its associated dog keeper, to the locked position, in which the roller of each dog engages the ramp portion of its associated dog keeper rolling thereon and onto the seating portion for securing the door on all sides to the structure.
