a housing having a front face and a rear face separated by a predetermined width;
a barrel having a first end extending perpendicularly from the front face of the housing and a second end extending to the rear face of the housing;
a locking actuation member disposed through the first end of the barrel;
a driver disposed through the second end of the barrel to engage the locking actuation member;
a first and second bolt, each bolt configured to engage the driver, where upon actuation of the driver via the locking actuation member, the first and second bolts move in opposite directions of each other in a perpendicular arrangement relative to the barrel, each bolt is generally rectangular and includes a first surface and a second surface, the first bolt further includes a first plurality of gear teeth parallel to the first surface along a first edge and the second bolt includes a second plurality of gear teeth formed parallel to the first surface along and edge opposite the first edge of the first bolt; and
an end plate configured to retain the driver and the first and second bolts in the housing,
wherein upon actuation of the locking actuation member by a key, the first and second bolts extend from the housing in a first position and at least partially retract within the housing in a second position,
wherein the first and second bolts are arranged in the housing in a parallel relationship such that the first plurality of gear teeth are spaced a predetermined distance away from the second plurality of gear teeth, and further comprising a round cog gear disposed between the first and second bolt and configured to engage the first and second plurality of gear teeth,
wherein each of the first and second bolts include an elongated slot positioned adjacent the respective plurality of gear teeth and the driver includes a cam that extends through the elongated slots and an aperture in the gear, wherein upon actuation of the driver, the cam rotates the gear to extend and/or retract the first and second bolts.
