A vertical bolt mechanism and installation configuration that avoids damage to a door corner comprises a vertical bolt case of tubular shape and a horizontal tubular transfer case. The mechanism is substantially contained within the bolt case and transfer case. In the installation in a door, the bolt case and the transfer case require only two major holes in the door top and edge, each hole being well spaced from the door corner and the axis of each hold being directed perpendicular to the other. Installation requires insertion of the bolt case through the hole in the top of the door and the transfer case through the hole in the edge of the door. The two cases come together to form an L-shape within the door with the internal mechanism of each case joined in engagement. Routing or cutting out of the door at the corner is thus avoided.
