ABSTRACT:
A lockable strike for walk-in cold rooms includes a housing that includes a recessed well with openings positioned on opposing sides thereof to accept a locking device therethrough and a deadbolt moveably engaged therein to reciprocally move along a path of travel between an extended position and a retracted position with respect to the housing; and a knob rotatably mounted within the recessed well and having an opening through a handle thereof positioned relative to the openings in the housing to further accept the locking device therethrough thereby preventing the rotation of the knob in a first position, wherein the handle can engage the locking device when it is inserted through the openings in the housing thereby preventing the rotation of the knob in a second position, and the knob is in communication with the deadbolt to move the deadbolt between the extended position and the retracted position when the knob is rotated.
