A pivoting member and sliding projection lock peg hooks in place, reducing shoplifting while allowing keyed access for authorized opening.

A wireframe rack lets bag dispensers slide in for easy loading, mount on varied surfaces, and stay secure while keeping graphics visible.

A magnet-mounted lock housing and spring plunger align hitch apertures quickly while reducing shank play and rattling in the receiver tube.

A lock housing blocks release lever movement to prevent both hitch ball removal and unauthorized trailer coupling.

A dual-loop wrench locks onto a fire hydrant with an eye bolt and padlock, preventing tampering while preserving operation with common tools.

A rotatable actuator and blocked fasteners let this padlock body accept replaceable cylinders while resisting screw or pin tampering.

End caps seal both sides of the U-lock body to block dust and particles, keeping internal parts clear for smooth locking and unlocking.

Interchangeable cylinder adapters let one padlock body fit multiple lock types while keeping a snug, concealed, tamper-resistant assembly.

A freely rotating two-clutch lock blocks hammer-driven pin movement, preventing sliding bolt release while preserving normal key unlocking.

Clutch fins with rounded edges and matched lengths obscure false gates and audible cues, making combination padlocks harder to pick.

A free-rotating dual-clutch lock blocks locking pin movement under hammer blows, preventing forced sliding bolt release.

An X-shape twistable cable and segmented rigidity reduce zipper pull tab damage while maintaining secure luggage locking.

A spring-biased secondary lock arrests the bolt assembly when the primary lock is displaced, preventing forced unauthorized unlocking.

Keyed shackle and bore segments stop leg rotation after cutting, preventing gap formation and unauthorized padlock removal.

An internal locking bracket and cover plate secure utility vault access while shielding the lock from weather, damage, and tampering.

A tight shackle-toe sleeve blocks bolt-cutter access and keeps the padlock secured even after part of the U-shaped shackle is cut.

An X-shaped twistable cable structure spreads bending force during luggage handling to protect zipper pull tabs while preserving lock strength.

Non-circular shackle tips lock into matching housing openings to block rotation attacks and force a second cut to defeat the hoop lock.

A segmented twistable cable and dual-lock structure absorb housing twists to reduce zipper pull tab damage during luggage transport.

A modular assembly reuses standard cylinder locks with separable rods, plates, or cables to secure varied items and form portable barriers.

A self-contained rotating disc-detainer unit uses at least 12 discs to increase lock combinations without complex assembly.

Spaced collars clamp helically wound rope strands to resist unravelling during cutting while preserving bending flexibility.

Nine false gates and one true gate complicate unauthorized decoding, while the reset plate enables code reconfiguration.

A secondary pocket and torsion spring require a precise rotor position before shackle extraction, reducing accidental disengagement.

An aluminum or aluminum-alloy shell clogs grinder grit around a hardened steel shackle, preserving compact U-lock security.

Spring-loaded key and recode indicators show whether a padlock was opened by key or combination, clarifying reset status.

A rotatable actuator and concealed fasteners support replaceable locking cylinders without replacing the entire padlock.

A reset button disengages combination clutches so both hands can set dials while key and combination locking remain independent.

Pre-aligned pivot device eliminates separate component alignment during installation, simplifying assembly while maintaining reliable lid locking function.

A core replaceable hockey lock uses a universal interface to hold different deadbolt cores within a single housing.

A distributed over-lock system transmits unlock codes via electronic messaging to enable immediate customer access without human intervention.

Segmented housing and angled guard plates block tool access to latch arms while spring bias ensures automatic engagement for tamper resistance.

A hoop lock assembly uses a shackle with straight and angled feet to engage independent locking mechanisms on the crossbar.

A padlock integrates key and combination mechanisms to independently control shackle movement for secure inspection access.

A padlock with a recessed main body accommodates the fastening bar and container edges to prevent external access.

An accelerometer detects housing displacement in an electronic locking device to trigger remote messaging and automated access control.

An oblong keyhole restricts drill bit insertion, and a one-piece actuator eliminates assembly joints that weaken security.

Reduced aperture disks nested in the standard stack expand combination levels without increasing lock housing dimensions or violating industry standards.

Segmented plates and a directional plate enable the spindle to disengage bolts during reset, resolving the conflict between high security and user convenience.
