The Master Lock Rollerball Combination Padlock does away with keys and number combinations that are tricky to memorize. Instead, this lock allows users to set a code using a series of directional movements up, down, left or right. This way, the locking combination can be set to any number of movements in sequence. For additional customization, passcode indicators like shapes, letters, numbers and symbols are also included with the Master Lock Rollerball Combination Padlock.
The inclusion of the moving ball piece in the lock also makes it possible for users to open the device with just one hand.
The unique padlock is ideal for students heading back to school, but it's also useful for gym, employee and general storage lockers.
