Master Lock 4684T TSA Lock 2-Pack review

The Master Lock 4684T is a straightforward 2-pack of set-your-own combination TSA locks for $21.99. Each lock has a 1-3/8 in (35 mm) body in bright colors that Master Lock says make luggage easy to identify, and a rigid shackle 3/4 in (19 mm) long and 1/8 in (3 mm) thick. Like the brand's other TSA models, Master Lock says it is recognized as TSA approved in 29 countries and that screeners can inspect and relock it without damage. It ranks below the 4688D because two of those single locks cost $19.98, slightly less than this pack, and the 4688D's braided shackle threads through more zipper pulls. The 4684T makes sense if you prefer the larger body and want both locks in one box, or if the 4688D colors you want are out of stock. Like other Master Lock store orders, it ships only to the contiguous United States. We compared documented features and published prices and did not test the locks.
