Locksets
 |
Two general kinds of locksets are available
for doors: cylindrical and mortise. A cylindrical lockset fits into a large hole bored into the door's face; a mortise lockset fits into a rectangular pocket cut into the door's edge. Exterior doors may have either cylindrical or mortise locksets. Interior doors usually have a cylindrical lockset operated with a push button, though some older homes may have interior mortise locksets. Exterior cylindrical locksets are operated by a key inserted into the exterior knob; the interior knob is operated either by a key or by a small push- or turn-button on the knob. An exterior mortise lockset normally has a deadbolt that is an integrated part of the locking mechanism—when you turn the key from outside, it releases both the knob and the deadbolt. |

If you are concerned about
security, be sure your exterior doors are protected by deadbolts with a
minimum 1-inch throw. |
