Three-dial combination lock for travel bags

The Master Lock 4688DBLU is a small steel-bodied padlock designed to secure luggage, backpacks, duffel bags and briefcases. Its front-mounted three-dial mechanism lets you set a personal combination without keys. The blue finish adds quick visual identification on a crowded carousel.

Steel body resists casual tampering

The 1/2 in thick steel body and 1/8 in diameter steel shackle deter opportunistic cutting or prying. No electronic components mean zero power draw and silent operation. Weather resistance is not rated, so prolonged heavy rain or submersion should be avoided.

Fixed shackle dimensions suit standard zipper

Shackle clearance measures 1 1/2 in height by 5/8 in width, fitting most bag hardware without forcing. The lock is not TSA-accepted, so agents may cut it during inspection. Registration of a control key is not required or supported.

Questions about this item

How do I set a personal code on the three dials of this 4688 lock?

Open the lock with the factory code, push the shackle down and hold it while you turn each dial to your chosen digits, then release the shackle to save the new combination.

What part of the 4688 lock is most likely to need replacement after repeated travel use?

The 1/8" diameter steel shackle can bend if forced through tight zipper pulls or struck during baggage handling, and it is the only moving component that takes physical stress.

What limit appears first when the 4688 lock is left on luggage through repeated trips?

The lock has no weather resistance, so moisture and grit will eventually stiffen the three dials and the shackle spring, making the combination harder to turn.
