3-Position Adjustable: Interlocking Male and Female
This can be adjusted in 3 positions over its 1" length. It must be
manually snapped into position, but the male-female attachment resists
sideways sliding.
Double magnets allow easy closure in 3 different positions and allow for
in-between attachment. The robust 5.4 kg (12 lb) holding power makes
it invaluable for items such as wallets, briefcases, and expanding
luggage.
