Glad Hand Lock Keyed Alike 20 Pack Heavy Duty Aluminum - Trailer

In this review of the Glad Hand Lock Keyed Alike 20 Pack the bottom line is simple: this kit is for fleet managers, dock supervisors and owner-operators who need a fast, physical way to 'dead-line' trailers during loading and unloading. The reviewer found the most convincing reason to buy is the straightforward theft and movement prevention offered by the cast aluminum glad hand locks that physically block the emergency air line connection, making it impossible to move the trailer while engaged. For operations that require repeated, reliable trailer lockout the 20-pack keyed alike set is an efficient choice.

Key Features

• 20 Pack: Supplies enough locks to secure multiple trailers or to outfit a small fleet without ordering individually.
• Cast Aluminum Construction: The heavy duty material resists denting and provides a durable barrier around the gladhand fitting.
• Keyed Alike: All locks use the same key, simplifying access for authorized staff and avoiding multiple key types to manage.
• Quick Install: The lock installs and removes in seconds so it fits into busy loading and unloading workflows.
• Effective Lockout: By encircling the emergency air intake the device makes it physically impossible to connect the trailer to the cab or move it while engaged.
• Includes Keys: The order contains 20 locks and 40 keys, giving a spare key per lock for convenience and backup.

Who It's For

The Glad Hand Lock 20-pack is aimed at trucking fleets, terminal operators and warehouses that need a low-tech but reliable way to immobilize trailers during loading, unloading or maintenance. It works well where a visible, mechanical deterrent is preferred over electronic solutions and where multiple units make centralized keying practical.

Those who should look elsewhere include drivers or small owners who need a single lock or a keyed-different system, and operations that require integrated electronic tracking or alarmed security devices rather than a manual gladhand lock.

Pros & Cons

• Keyed alike system and included spare keys reduce key management hassle.

Cons

• Only provides mechanical immobilization and no electronic alert or tracking capability.
