Heavy Duty Cargo Door Lock for Shipping Containers - Maximum Security Trailer Lock for Semi Trucks (Combination)

About this item

• CONTAINER & SEMI TRUCK DOOR LOCK: The Heavy Duty Cargo Door Lock is our number one selling device. It fits vertical cargo door bars from 9 ¾”-16” apart (extension kit available, sold separately), and is the ideal security solution for sea and construction site storage containers and over-the-road trucks.
• MAXIMUM SECURITY: This heavy duty door lock system is built to secure semi-trailers and sea containers by locking the innermost vertical locking bars together. It features a tamper-resistant tubular pin tumbler lock design for ultimate peace of mind while you’re away.
• COMBINATION SECURITY LOCK: Four-digit combination locks are ideal for multiple users who need to unlock containers or equipment without several sets of keys circulating or getting lost.
• EASY OPERATION: No mounting required. Separate the two halves of the Cargo Door Lock, aligning them so the lock mechanism and holes are both facing downward, and install one half of the Cargo Door Lock on each doors’ locking bar. Slide the two halves together by inserting the smaller tube into the larger tube. Secure the Cargo Door Lock as tight as possible on both doors' locking arms and depress the locking button with key removed or turn dials.
• HIGH QUALITY: Distinguished by its signature red finish, every lock is protected by a steel-locking structure that can withstand thousands of pounds of force. But it doesn’t stop there! Each device is powder coated before a series of quality assurance checks to ensure security and reliability.
