what is the difference between 2 lever and 3 lever lock?
Lever locks are supplied in a number of variants - 2 lever, 3 lever, 4 lever and even 5 lever. ... Also, the fewer the levers, the lower the security as the lock might be easier to pick. A 2 lever lock will be most suitable for your internal doors such as bathroom and bedroom doors, where high security is not a priority.
