Abstract
Abstract A highly tamper-resistant lock for attachment to an electric meter box, as a supplement to other locking means, if any, or a replacement therefor, the lock having one part secured to the box and a separable part adapted to be locked in engagement with the first part and in a position to prevent separation of the parts to project in front of the meter box cover to prevent opening thereof. The part secured to the box includes a reinforcement member having at least one wing piece which engages a portion of the separable part in the locked position to prevent tilting of the separable part by prying. The lock for the separable part is shown as a plunger type lock, to be inserted in a deep tubular chamber.
