A lockable clamping device for securing an object on a mounting surface is disclosed herein. The lockable clamping device comprises a first tab configured to extend over the object at one side. A second tab is engageable with the first tab and configured to extend over the object at another side. A lock tab facilitates assembly of a locking device to interlock the first and second tabs, thereby securing the object on the mounting surface.

A securing device for securing a wing nut type ferrule clamp installed on a ferrule, the securing device has a top and a hollow body that extends downwards from a periphery of the top. The hollow body has a front face and a rear face, the front face has an elongated hole configured to receive one end of the wing nut. A first cutout in the front face extends from the bottom of the hollow body and below the elongated hole. The first cutout has a width more than the width of the ferrule clamp. The rear face of the hollow body has a second cutout to receive an opposite end of the wing nut. Two flanges extend from opposite edges of the second cutout, wherein each of the two flanges has a hole. A shackle can pass through the two holes and limits the movement of the wing nut.

A lockout device is able to secure a door on a panel. The lockout device includes a housing and a flexible line. The housing has a first mounting portion adapted for securement to one side of the panel and the flexible line has on one end thereof a second mounting portion adapted for securement to another side of the panel from the first mounting portion. The housing further supports at least one line engagement element, and the flexible line extends through at least a portion of the housing including the at least one line engagement element for selective engagement therewith. In use, the mounting portions may be affixed or attached to opposing sides or edges of the panel, the flexible line drawn taut, and the line engagement element(s) of the housing used to engage the flexible line to hold it in position with respect to the housing.

A system and method for securing a locked-out component is provided. One embodiment slides a slidable blade of a lock out controller from a lockout position to a release position, wherein an inside connector between the slidable blade and a piston of a lock out attachment pushes the piston from a hook lock position to a hook extended position so that a hook is extended outward from the lock out attachment; coupling the hook to the locked-out component; and sliding the slidable blade of the lock out controller from the release position to the lockout position, wherein the inside connector coupled between the slidable blade pulls the piston from the hook extended position to the hook lock position, and wherein the hook is retracted substantially back into the interior of the lock out attachment so that the locked-out component that is coupled to the hook cannot be accessed by a tool.

A clamping cable lockout device includes a pair of clamp jaws that are supported by a body and an arm movable relative thereto. A jaw release permits a one-way ratcheting of the arm relative to the body to reduce the distance between the jaws unless the jaw release is actuated to a release position. The device also has a cable having an end secured to the body and a free end. A cable securing mechanism is supported by the body and has a lockable cover selectively permitting access thereto such that, when the cable securing mechanism receives the free end of the cable and the cover is closed, a closed loop by the cable which can only be made smaller. The lockable cover has a blocking arm that, when lockable cover is in the closed position, prevents actuation of the jaw release to the release position.

A supplemental locking device particularly suited for use on a cargo container. The device consists of a three-sided channel, made of heavy-gauge steel that fits over the locking mechanism of a cargo container capable of being slipped over this locking system with the aid of oval cut slots on the sides that accommodate any horizontal members.

A blocking mechanism for preventing the opening of a tail gate on a vehicle having a hitch member, the blocking mechanism comprising a triangularly shaped frame having two horizontal members and two diagonal members, wherein each of the two diagonal members include an upper and lower end and each of the two horizontal members include a proximal and distal end; the lower ends of the two diagonal members are rotationally connected to a connecting bracket and the upper ends are attached to angled brackets, wherein the connecting member is attached to hitch member; the distal ends of the two horizontal members are attached to the angled brackets and the proximal ends are joined via a pair of connection elements; and a padlock is configured to lock the pair of connection elements.

An improved mount for receiving a padlock to securely enclose a case includes a pair of aligned holes and aligned indentations formed in the lid and the container body. The padlock mount includes a saddle formed between one of the holes and indentations, with a peripheral sidewall to restrict rotational movement of a padlock shackle. A padlock receptacle receives the padlock body in a recessed area to protect it against damage and restrict movement.

Locking mechanisms and toolboxes including locking mechanisms are disclosed herein. In one embodiment, a locking mechanism includes a frame including an opening, a lid, a latch coupled to the lid, the latch including a latching post and a flange, and a locking device including a draw mechanism coupled to the tab, where the draw mechanism is translatable with respect to the frame, the draw mechanism including a slot that includes a narrow end and a wide end positioned opposite the narrow end, where the flange has a width that is greater than a width of the narrow end of the slot of the draw mechanism, and where the draw mechanism is repositionable between a latched position in which the narrow end is axially aligned with the latching post of the latch and an unlatched position, in which the wide end is axially aligned with the latching post of the latch.

The trailer emergency air brake supply line coupler is movable between a control position, where air pressure in the supply line causes the trailer emergency air brakes to release so the trailer can be moved, and a park position where the trailer emergency air brake system is vented to automatically engage the trailer emergency air brakes. The lock includes a metal frame attached to the trailer proximate the trailer coupler. First and second spaced side walls extend from the rear wall of the frame on opposite sides of the trailer coupler. A retractable pin extends between the side walls and intersects the path of movement of the supply line coupler preventing movement of the supply line coupler between its control position and its park position. A lock cylinder, padlock or other mechanism retains the pin on the frame.
