A lockout system includes a hasp assembly and a plurality of tags. The hasp assembly has a back plate defining slots each sized and shaped to receive a tag. The back plate and tags each have openings that align when a tag is received in a slot. A first hasp portion has a first loop portion and a second hasp portion has a second loop portion. The first and second hasp portions are rotatable with respect to one another such that moving the lockout system has both an unlocked position and a locked position associated with an open position and a closed position. In the closed position, the first and second hasp portions complete and define a closed loop, where one or more tags can be installed in slots preventing further movement from the closed position.

Security devices including a lock, shroud, and plug are described. In embodiments the security devices include a shroud that includes a shroud sidewall having an inward facing surface and an outward facing surface. The security devices further include a lock that includes a barrel, wherein the lock is integral with or coupled to the shroud to define a shroud cavity between an outward facing surface of the barrel and the inward facing surface of the shroud sidewall. The plug includes a proximal end, a distal end, and a plug sidewall receivable within the shroud cavity. The plug sidewall includes an inward facing surface defining a plug cavity configured to receive the barrel of the lock therein. Such security devices may be advanced from an assembly state to an unlocked state, and may then be reversibly moved between the unlocked state and the locked state. Security device kits are also described.

A tamper proof locking mechanism incorporating a first fixture for attachment to an index protective cover, a second fixture for attachment to an instrument, and a third fixture for connecting the first fixture to the second fixture. The first fixture may have a receptacle, the second fixture may have a plate with an opening, and the third fixture may have a protrusive structure that fits into the receptacle of the first fixture and into the opening in the plate to connect the first fixture to the second fixture. The protrusive structure may have a rivet that is partially embedded with a plastic-like material that reveals tampering when an attempt is made to break a connection between the first fixture and the second fixture.

A lockout system includes a hasp assembly and a plurality of tags. The hasp assembly has a back plate defining slots each sized and shaped to receive a tag. The back plate and tags each have openings that align when a tag is received in a slot. A first hasp portion on the back plate defines part of a closed loop. A longitudinal locking bar is slidable along the back plate and has notches shaped to receive ends of the tags. Moving the locking bar between an unlocked position and a locked position operates the second hasp portion between an open position and a closed position. In the closed position, the first and second hasp portions complete and define the closed loop, where one or more tags can be installed in slots with the first end of the tag engaging a notch to lock closed the hasp portion.

The instant disclosure relates to an apparatus and method for securing a watthour electrical meter to a socket meter box. A locking ring comprises a divided annular band fitted with tab members configured to accept a variety of ring fasteners. The tab members support a variety of ring fastener and fastener receiver assemblies, and have complementary mating surfaces that substantially mate around the head of an installed meter so that the locking ring is tamper-resistant. The ring fastener and fastener receiver have a number of complementary apertures disposed to receive either wire seals or other locking mechanisms.

A shielded locking system for securely closing a lid on an enclosure, such as a grade level utility vault, including an L-bolt connected to a spring-biased slide member positioned on the underside of the lid that rotates in a slotted housing that securely retains the L-bolt under the lid, the slide member engaging an abutment on the inside of the enclosure when the lid is forced down over an opening in the enclosure by downward force on the lid which progressively causes the latch to retract against the spring-bias from contact with the abutment and then snaps the latch into a spring-biased locking position under the abutment, and a non-conductive cover positioned over and connected to the locking system to shield the L-bolt from electrical conductivity from within the enclosure.

A pit assembly comprises: a pit wall defining an inner surface, and an outer surface; a rail secured to the inner surface of the pit wall, the rail comprising: a top end, a bottom end, a first side end, a second side end, and an outer face defining a curved radially outer surface and mounted on the inner surface of the pit wall; a center-lock strike portion proximate to the first side end; and a side-lock strike portion distal from the first side end, a one of the center-lock strike portion and the side-lock strike portion defining a strike notch in the bottom end; and a lid defining an upper surface and a lower surface and comprising a locking mechanism, the locking mechanism coupled to the lower surface and configured to engage a one of the center-lock strike portion and the side-lock strike portion of the rail.

A utility enclosure includes a box having a plurality of walls and a central opening. An insert is positioned in the central opening and includes a plurality of connected side walls. A removable cover is connected to the insert. A removable lid is connected to the box.

A locking system includes a tamper-resistant lock and key. The tamper-resistant lock includes a cylindrical lock body with external threading on at least a portion thereof and a bore extending into an end of the cylindrical lock body. The bore includes an engagement feature disposed on the wall that defines the bore, and the engagement feature is disposed a particular distance away from the bore opening. The key includes a collar that has a cylindrical key body that fits within the bore of the cylindrical lock body. The cylindrical key body also includes an opening defined by the collar sidewall, a retractable engagement member at least partially disposed within the opening, a spring disposed within the collar, and a plunger disposed within the collar that is operable to engage the spring and has a recess sized and shaped to accommodate the retractable engagement member.
