PUCK Padlock Design

Protect the Lock. Protect the Asset.

Cobra PUCK padlocks move the locking point inside the padlock body rather than leaving a traditional shackle exposed. The result is a compact locking platform designed for applications where physical protection and key control matter.

01

Hidden Shackle

The shackle is enclosed within the padlock design, reducing direct exposure to cutting.

02

Cylinder Choice

Select the lock cylinder and key-control level that best fits the application.

03

Material Options

Choose from aluminum, steel and stainless steel configurations for different environments.

04

Serviceability

Select Cobra designs allow cylinders or components to be changed instead of replacing the entire padlock.

Need More Clearance?

A PUCK Padlock Designed Around Fit
