We now carry a great line of reproduction hardware from Nostalgic Warehouse. A mortise lock is actually a mechanism box, like you see in the image above, and of the dimensions mentioned in the description. A mortise lock requires special preparations to make it work, you probably don;t want to order this type of lock unless you are replacing an older set, or if you can have your door shop custom prepare your doors.
As the need for restoration hardware became more and more prevalent, Nostalgic Warehouse met the need with their mortise lock. This great mortise set replaces most old style mortise locks. The great thing about Nostalgic Warehouse's line is that you can also get the old vintage look of crystal knobs or old Victorian style door knobs [with backplates] with standard tubular latches to fit newer standard fitting doors.
A latch mechanism is the cylinder that is driven through the edge of the door. This is often also called a tubular latch mechanism. The mechanism has a spring loaded latch that retracts to open the door and upon release of the door knob or lever, protrudes to keep the door closed. A tubular latch mechanism for an exterior door often comes with an attached mortise plate, and requires mortising, or some chiseling to be done on the edge of the door for the plate to rest correctly recessed in the door. "
The image above shows the latch mechanism with an attached mortise plate. The mortise plates not only look nice, they provide added security. This post has two door hardware terms that are good to know: Tubular latch, or latch mechanism - The cylinder driven through the edge of the door with a spring loaded latch that keeps the door closed, or allows it to open. Mortise Plate - The plate on the edge of the latch mechanism that provides additional security and a nicer, cleaner look.
Backset - The backset on a door is the distance from the edge of the door, to the center of the bore hol in the door. See the following image:
While you are shopping on Direct door hardware, remember that most Door Knobs are shipped with an adjustable backset in the box. This adjustable backset should accommodate any standard door. Some of our more expensive door hardware, and restoration hardware products require a backset to be specified upon ordering. If you are replacing older door hardware, please check the current backset so that we can send you the right stuff.
Ball catches are generally used on closet doors, but can be used in other applications. The way they work is simple: on the top of the door there is a hole drilled and a spring loaded ball is installed which slightly protrudes from the top of the door. On the jamb above a strike plat is installed much like a strike plate used on a regular door, but this strike has a small indentation to fit the contour of the ball rather than a hole for the latch. As the door shuts, the spring loaded ball rests in the indentation on the strike and keeps the door closed.
Bore or Bore Hole
The bore hole simply put, is the large hole drilled in a door through which the main assembly of a knob-set is installed.
A deadbolt is a locking mechanism that mounts much like a door knob. Most exterior doors are locked with a door knob, and also a deadbolt. The deadbolt bore hole is directly above the door knob hole. When a lever is turned, a solid steel cylinder is inserted deep into the door jamb to securely lock the door. Deadbolts are available as single or double cylinders. Single cylinders are keyed on the exterior and have a turn lever on the inside. Double cylinder deadbolts are locked or unlocked with a key from the inside and the outside. Double cylinder deadbolts should only be used in special situations as a single cylinder is much safer in emergency situations.
Door hinges are made of two metal plates that are attached together with a removable pin. The metal plates are attached to the door and door jamb with screws. Hinges hold the door securely to the door jamb and allow it to swing open and closed.
The door stop is the piece of molding that runs vertically on the jamb, and is roughly 1" in width. The door stop "stops" the door in the jamb and keeps it from opening the opposite way. The door stop also hides the gap between the jamb and the door. Spring stops are also often referred to as door stops.
Nope this is not an apparatus that helps you look at doors. A door viewer is a cylindrical viewer with curved lenses on the inside that magnify the view on the other side of the door. Door viewers are available in a various degrees of viewable area. These viewers are easily mounted in the door by drilling a hole at eye level and installing the viewer. Door viewers are a great addition to your exterior doors and increase the security of your home by allowing you to view who is outside before opening the door.
Also sometimes called dummy trim. These knobs are used most often on doors with ball catches, or whenever you have a door that is not bored for a complete door knob set. Dummy knobs are usually sold individually and include one knob or lever that mounts directly to the face of the door with screws.
Decorative tip that attaches to the top and or bottom of a door hinge pin. Not all hinges can accept finials, you must order hinges that are designed to have them.
Flush bolts are most often used on french doors. They are mounted [flush] on the inside edge of a door or door stile. By simply pushing the button on the flush bolt up, a bolt is inserted into the jamb and secures the door closed in the middle. Flush bolts are often used on the top and bottom of french door applications. This allows one side of the french door to be fixed while the other door closes against it; then the fixed door can be easily opened when needed.
The door jamb is the wood frame that surrounds the door in the doorway. Its important for a door to have a good solid jamb for the door to close against. It's especially important to have a good jamb on an exterior door where a deadbolt will be used. The strike plate attaches to the jamb, and holds the door closed by catching the latch mechanism.
A keyway is the actual key cylinder that is inserted into the door knob. When a door knob is unlocked, the key is inserted into the keyway and the lock mechanism is unlocked as the key turns. Keyways can be removed and changed for security reasons or to key several locks alike. Keep in mind that not all keyways are made a like so when you order different brands, there is a good chance they can;t be keyed alike.
A knob is generally a round shape which is used to grab with your hand and open a door. Knobs are made of brass, zinc die cast or other products.
The latch is the mechanism that slides into the enge of the door and retracts or protrudes with the turn of the door knob. The latch keeps the door closed and when the knob is turned allows the door to open.
Lever, Lever Handle
A lever or lever handle has the same functionality as a door knob, but has a different appearance. A lever is longer and thinner with a fancier look. Keep in mind when ordering lever handles that you may need to specify the swing of the door so that your lever handles point in the right direction when installed.
Refers to a hinge pin that cannot be removed. Used mainly where security is needed, so that the pin cannot be removed, and door removed from the opening. On exterior doors which open outward, the pin is on the outside of the building. In this case, these pins may be used more often.
The plate or trim piece behind the knobs that attaches the knob to the door.
A strike plate is the metal piece attached to the door jamb. As the door closes, the latch mechanism strikes the plate mounted to the jamb and the strike plate catches the mechanism and holds the door closed. Strike plates are generally the same finish as the door knob set and mount to the jamb with screws provided.
