Rotation Restricted Locking Apparatus and Method
First Claim
1. A rotationally-actuated barrel lock for use with locking hardware comprising a rotation restricting stop surface, the barrel lock comprising:
- a body comprising a head and a shank connected to said head;
at least one rotation restricting stop surface located on said body for interaction with the rotation restricting stop surface of the locking hardware; and
at least one variable-radial-play and radially-retractable retainer having an acute retaining surface, wherein the radial play allows the retainer to protrude through said body in a first condition and retract into said body in a second condition.

Abstract
An example embodiment relates to preventing rotation of a barrel lock when opened by a key. At least one example embodiment includes a rotationally actuated barrel lock for securing electric meter boxes and the like, and a spring loaded clip for mounting inside the meter box. Lock actuation is characterized by rotation of a key relative to the lock. The barrel lock includes a head portion, and a smaller diameter shank portion with flatted areas thereon. The clip includes, in an example embodiment, a lock receiving opening with internal protrusions which engage the flatted areas on the lock shank, thereby preventing rotation of the lock when it is engaged by the key.
