Quick Answer: The Master Lock 4688T is a 2-pack of TSA-accepted, 3-dial combination cable locks designed for checked luggage, backpacks, and carry-on bags. TSA agents can open and relock these without damaging them, and the resettable combination means no keys to lose. Backed by a Limited Lifetime Warranty.

Standard padlocks on checked luggage get cut off by TSA screeners during security inspections — leaving your bag unsecured for the rest of the journey. Master Lock’s TSA-accepted locks solve this by giving TSA agents a universal access key to open, inspect, and relock your bag without touching your combination. You set your own 3-digit code, and the flexible braided steel cable fits through most luggage zipper pulls.

Two locks in one pack means you can secure both a suitcase and a backpack, or keep a spare for your next trip. The resettable combination eliminates the need to carry keys, and the vinyl-coated braided steel cable is built to handle the rough treatment of baggage handling equipment. Master Lock is a well-established US security brand with a Limited Lifetime Warranty on this model.
