Figure 6-30.—Parts of a cylinder lock.The door should now be placed in the opening andblocked up at the bottom for proper clearance. The jambshould be marked at the hinge locations, and theremaining hinge half routed and fastened in place. Thedoor should then be positioned in the opening and thepins slipped in place. If you have installed the hingescorrectly and the jambs are plumb, the door shouldswing freely.LocksThe types of door locks differ with regard toinstallation, cost, and the amount of labor required to setthem. Some types, such as mortise locks, combinationdead bolts, and latch locksets, require drilling of theedge and face of the door and then routing of the edgeto accommodate the lockset and faceplate (fig, 6-29,view B). A bored lockset (view C) is easy to install sinceit requires only one hole drilled in the edge and one inthe face of the door. Boring jigs and faceplate markersare available to ensure accurate installation.The lock should be installed so that the doorknob is36 to 38 inches above the floor line. Most sets come withpaper templates, marking the location of the lock andsize of the holes to be drilled. Be sure to read themanufacturer’s installation instructions carefully.Recheck your layout measurements before you drill anyholes.The parts of an ordinary cylinder lock for a door areshown in figure 6-30.
