Know what you are looking for

First, let's start with the basics. If you're new to Baldwin Hardware, you might not be familiar with some of the terms used to describe our products. Here are a few key terms to know:


Door Types


If you are buying hardware for more than one door, please provide a count of how many doors by type.

  • Passsage
    (non-locking knob or lever set)
    Ideal for closets and storage spaces.
  • Privacy
    (locking knob or lever – no key)
    Ideal for bathrooms and bedrooms.
  • Keyed
    (locking knob, lever, entrance set or deadbolt for security)
    For exterior and higher security needs.

Door Preparation


  • Tubular Locks
    Prepared for Tubular Locks
    Pre-Drilled with One or Two Holes
    The tubular style lock is commonly found on all types of doors, most notably interior residential and office doors. It boasts excellent security for most applications and is usually quite easy to install and replace if standard bore holes are already cut in the door. Make sure your new latch has the correct backset length (the measurement from the edge of the door to the center of the bore hole), and just follow the installation instructions. The most popular types of tubular style locks are single cylinder and double cylinder.
  • Mortise Locks
    Prepared for Mortise Locks
    Pre-drilled with a Pocket in the Side of the Door
    A mortise style lock is the most secure form of an entry set. The reason? A special cut in the door allows a longer and thicker mortise to slide into the pocket in the door itself, providing superior protection. These types of locks require special door preparation, so if your door isn’t currently cut to fit this kind of lock, you (or a professional installer) will need to use a mortise saw to cut into the door so the lock fits properly. Take note that not all mortise locks have the same dimensions. So prior to any door alteration, take careful measurements.
  • Blank Door
    No Holes or Pockets

Door Measurement

TIP: Measure, measure, measure. And then go back and check your measurements.


  • Measure Door Thickness
    Door Thickness

    Measure the door from the inside to the outside.

    For example, many interior doors measure 1-3/8” thick and the industry standard for front doors is 1-3/4”. If you have a custom door that is thicker, don’t worry. Your representative can order longer components that connect the hardware from one side of the door to the other.

  • Measure Door Height
    Door Height

    Measure the door from the bottom sill to the top of the door.

    Standard door heights are 6’ 8” but, can be higher. This measurement is important is you are planning to purchase new hinges.

  • Measure Stile Width
    Stile Width

    Measure from the edge of the door to the edge of any molding, raised panels or glass in place on the door.

    Narrow stiles (4” or less) may limit some of the backset or trim options for your knob or lever.

  • Measure Backset

    Measure from the outside edge of the door to the center of the bore hole.

    This is the distance from the edge of the door to the center of the knob or shank on the lever.

  • Measure Center to Center
    Center to Center

    Measure from the center of the top hole (deadbolt) to the center of the bottom hole (latch).

    This measure is needed when shopping for exterior door handle sets or on interior doors where you have two pre-drilled holes.

Door Handing

Door Handing

This a term used to describe which way your door is hinged. To determine the handing of a door, stand on the side of the door from which you gain access to the room. (exterior door = street side; room door = hall side; closet door = room side; other doors = side where hinges are not visible). Face the door. Notice which side the hinges are on.

Left Handed: hinges on left, door swings into the room
Left Handed Reverse Bevel: hinges on left, door swings out of the room
Right Handed: hinges on right, door swings into the room
Right Handed Reverse Bevel: hinges on right, door swings out of the room
