Each padlock has a steel shackle and 4 pin cylinder with single locking feature. Tested up to 48 hours for corrosion resistance to ensure protection against different weather conditions. The Yale Locks Brass Padlocks are constructed from hard wearing boron, and are rigorously tested against corrosion.
Lovely little pair of padlocks and slightly larger than I was expecting. 20mm size is perfect for locking large suitcases. Good solid Yale brand, nice and secure.
