Welcome to our shop! Introducing our compact, lightweight TSA-certified luggage lock made of high-strength zinc alloy. This lock is designed to be covered in plastic to prevent scratching your luggage. Featuring a resettable 3-dial TSA combination lock, you have the option to choose from 1000 unique combinations. Unlike rigid locks, our TSA cable locks are flexible enough to pass through all standard size zip and hard case keyholes. These locks are truly the best for your travel needs. Material: Zinc alloy Lock rod thickness: 4mm Lock bar spacing: 1400mm To set the password: 1. Start with the password wheel at the initial position (password: 0-0-0). 2. Use a pen tip or a slightly sharp object to press the coder lever inside (keep the pressure down and do not release it). Turn the password wheel to your desired password and release the pressure to set the password. 3. After setting the new password, please test it first before using it. It is recommended to disrupt the password after testing for added security. 4. To open the lock, gently press the metal protrusion on the right side when the correct password is dialed. You will receive one password lock. 100% Satisfaction: Our customers are our top priority.
