Whats the difference between a 3 lever and a 5 lever lock?
Basically as is state, some locks have 3 levers others 5, the levers usually have their bellies cut away at different depths, the lock bolt will sit through these holes an turn the levers up and down like there on a camshaft with the turn of the key, its these levers moving that will operate the lock system., so it’s a judge for yourself, whether you want 3 levers or 5, but 5 will generally offer a more secure level.
