Master Lock 4696T Combination TSA Luggage Lock 2 Pack Review (2026)

Who this two pack is built for

The 4696T targets travelers and gear owners locking equipment cases, golf bags or larger duffels that have a built in hasp or loop rather than a simple zipper pull. Because the shackle is longer than Master Lock's standard travel locks, it can wrap around thicker hardware that a short shackle would not reach, which matters for hard cases with integrated locking hasps as much as for luggage. Getting two locks in one purchase also suits anyone securing a case at both ends or locking two separate bags on the same trip without buying locks separately. It is a weaker fit for someone who only needs to clip a light daypack zipper shut, where a shorter, flexible shackle is easier to maneuver into place.

Body, shackle and combination explained

Each lock has a 1 5/16 inch, 35 millimeter wide metal body and a steel shackle that is notably long for a travel lock, at 1/4 inch, 6 millimeters in diameter and 1 7/8 inches, 48 millimeters long. Master Lock describes this as an extended reach shackle built specifically for equipment cases, and it is made of steel for resistance to cutting and sawing rather than being a flexible braided cable. The combination is a set your own four digit code, one digit more than the three digit dials on Master Lock's smaller 4688D lock, which adds a modest number of extra code combinations. Like the rest of the range, it is recognized as a TSA accepted lock in 29 countries, so screeners can open, inspect and relock cases without cutting the shackle.

Using it on equipment cases and larger bags

In practice, the extended shackle is the whole point of this lock: it is meant to loop around a case's integrated hasp or a thicker zipper pull assembly that a short shackle cannot clear, not to squeeze through a narrow backpack zipper. Because the shackle is rigid steel rather than a cable, it does not flex to find its way through an awkward or slightly misaligned opening, so it works best where there is a clear, fixed loop to pass it through. Setting the four digit combination is a one time task, and the same debris sensitivity that affects any dial lock applies here, so keeping the dials clear of dust and grit after checked flights helps them turn smoothly. Two locks in the pack means one can stay on a case at home as a backup while the other travels.

How it compares with Master Lock's cable and keyed locks

Here the site's original pro of a flexible shackle does not hold up against Master Lock's own published specifications, which describe the 4696T shackle as rigid steel built for extended reach rather than a bendable cable. The flexible, vinyl covered braided shackle instead belongs to Master Lock's shorter 4688D combination lock, which threads through narrow zipper pulls more easily but cannot reach around a thick equipment case hasp the way this longer shackle can. Compared with the keyed 4683Q four pack, this lock trades a shared key for a memorized code and gets a longer reach in exchange for a shorter, thinner shackle on the keyed set. Choosing between them comes down to what you are locking: a hasp or thick loop favors this lock, while a standard zipper pull favors the shorter cable or keyed options.

Verdict and who should choose a different lock

With a score of 7.8 out of 10 in this guide, this two pack earns its place mainly on value and fit for the specific job of securing equipment cases and larger bags with an extended shackle. It suits travelers with hard cases, golf bags or gear that has a built in hasp needing a longer reach than a standard travel lock provides. Anyone locking a simple backpack or suitcase zipper pull, where a shorter, flexible shackle is easier to maneuver, will likely be better served by the 4688D combination lock or the keyed 4683Q four pack instead, since both use shorter shackles suited to narrow openings rather than the extended reach built into this lock.
