This combination lock allows users to set their own combination and change it anytime. With a simple twist and push of the shackle, the combination can be set in less than twenty seconds, and users can change it as many times as needed. It uses a four-digit combination, which is more difficult for thieves to crack and easier for users to remember, as the combination can be set to a pin or birth year. The lock has an ultra-durable zinc alloy body and a hardened steel shackle, which can withstand rough airport handling. It features high contrast white-on-black dial numerals and a combination window for easy reading of the combination. The lock is 100% TSA approved, allowing TSA agents to inspect luggage without cutting the lock. Its recommended uses include travel lock, combination lock, small lock, luggage lock, TSA approved luggage lock, cable lock, golf bag lock, carry-on lock, suitcase lock, gym locker, toolbox, and pelican case. Color: Orange.
