About This TSA APPROVED- NO MORE CUT LOCKS: Certified TSA locks allow airport security to inspect and re-secure your bag with a master key, protecting both your lock and your luggage. CORROSION-RESISTANT ALUMINUM BODY: Chrome-plated 22mm aluminum body stands up to rain, humidity, and the wear of frequent travel without rusting or fading. PICK-RESISTANT LOCK CYLINDER: A precision brass tumbler makes these locks significantly harder to defeat than standard travel locks. HARDENED STEEL SHACKLE: Resists bolt cutters and tampering, so your bags stay secure from check-in to baggage claim. SMALL ENOUGH TO GO ANYWHERE: At just 22mm, these compact locks fit virtually any luggage zipper pull — carry-ons, checked bags, duffel bags, and backpacks; without adding bulk to your bag.
