Shop Cabinet HaspMatch the Padlock to the Security Risk
The correct padlock depends on more than the size of the lock. Shackle exposure, body material, environmental conditions, key control and the design of the hasp all affect the overall security of the installation.
For exposed or high-risk applications, a hidden-shackle PUCK padlock can reduce access to a common attack point. Other applications may benefit from conventional high-security padlocks with hardened shackles and advanced key systems.

- Exposed or protected shackle design

Hidden-Shackle PUCK Padlocks
PUCK-style padlocks conceal the locking interface, reducing direct access to the shackle and making conventional cutting attacks more difficult.

Shop Padlock HaspsPadlocks Can Be Part of a Larger Key System
Commercial padlocks do not have to operate as isolated locks. Depending on the product and cylinder system, padlocks can be configured keyed alike, keyed different or within a master-key hierarchy.
That allows padlocks to support facility-wide, fleet-wide or multi-location access strategies while maintaining appropriate control over authorized keys.

Frequently Asked Questions About Commercial Padlocks
What is a high-security padlock?
A high-security padlock combines stronger physical construction with enhanced cylinder and key-control features designed to provide greater protection against unauthorized access than basic commodity padlocks.
What is a PUCK padlock?
A PUCK padlock uses a rounded body that conceals the locking interface rather than leaving a traditional shackle exposed. This design can reduce access to common cutting and prying attack points.
Can commercial padlocks be keyed alike?
Yes. Many Cobra, ABLOY and Medeco padlocks can be configured keyed alike. Depending on the system, keyed-different and master-key configurations may also be available.
What padlocks are suitable for outdoor use?
The best choice depends on the environment. Body material, shackle construction, protective covers, corrosion exposure and keyway design should all be considered for outdoor applications.
Are padlock hasps important?
Yes. A padlock and hasp work as a system. A strong padlock attached to a weak or exposed hasp can still leave the overall installation vulnerable.
Where can I purchase these padlocks?
Padlocks featured on LockingSystems.com can be purchased directly through LSI Depot, including Cobra Lock, ABLOY, Medeco and compatible hasp solutions.
