The components of a lockset can include (but are not limited to) the door handles (commonly both inside and outside), latch bolt, dead bolt, face plate, strike plate, escutcheon, thumbturn, push button, turn button, and other trim.
Definition of lock strike
: a metal fastening on a doorframe into which the bolt of a lock is projected to secure the door.
A latch bolt is the part of a door that keeps the door from coming open. In order to be a latch bolt, the item needs to slide into place. This separates the latch bolt from chain locks or hooks, where the fastening mechanism is simply placed in a holder.
The Bore hole is the large diameter hole where the door knob is mounted. The standard sized bore hole is 2 1/8" in diameter. Through the edge of the door there is a 1" cross bore that extends from the edge of the door through the bore hole. This cross bore is where the latch is installed.
Passage door knobs are similar to dummy door knobs. They don't lock but are used to open doors and go between rooms. Passage door knobs are ideal for interior hallways, closets and other rooms that don't need privacy locks. They're also called unkeyed knobs.
The tailpiece is the part of the lock that extends from the outside housing (where you insert your key), through the bolt, to the interior thumb turn. Its rotation is what mechanically actuates your lock.
Latch. A door latch is a shaft that protrudes from the edge of a door panel and into the door frame securing the panel in place. When the handle is turned, the latch retracts allowing the door to be opened.
Deadbolt Strike:
It basically covers the part of the jamb where the hole would be and the bolt would lock into place. Dresses it up a bit. Most of the hardware comes standard with the full lip strike, but are available with pretty much any of the styles listed upon request.
Passage Latch Function
The latching mechanism can be retracted by both the inside and outside levers at all times. This door lock function is never locked and has no key or locking mechanism on either side of the door. It is often referred to as a passage latch instead of a lock.
The main types of door functions are Passage (doors that don't require locking), Privacy (a door that can be locked by a button on the inside), Dummy (has no mechanical latch and acts only as a pull), and Interior Mortise (door with an active latch with skeleton key lock).
But the word doorknob most often specifically refers to a handle shaped like a knob—a part that sticks out and has a rounded end. Door handles in other shapes might be called doorknobs, but it's more likely for them to be called door handles or just handles. Another difference is that doorknobs typically turn.
For example, a doorknob is an example of a wheel and axle in which the knob itself acts as the wheel, and the shaft of the lockset acts like the axle. It is important to note that the “wheel” in this scenario does not have to act like a wheel at all, but is a rounded object that rotates.
An additional latch that automatically deadlocks the main latchbolt when the door is in the closed position. Term is usually used with mortise locks. Security Center.
Vestibule Lock: The latch is retracted by a key from outside when the outside lever is unlocked by key in the inside lever. The inside lever is always free for immediate egress.
Office Lock function is defined as a lock where the latch bolt operated by lever from either side unless outside is made inoperative by key outside or by turning inside thumbturn. When outside is locked, latchbolt is retracted by key outside or by knob/lever inside.
Combined Interior Door Knobs
You get both Hall & Closet and Bed & Bath functionality in a single lock. Lock adapts to the ever-changing life of the room – from nursery to bedroom to office and back again without ever taking the lock off the door.
Privacy knobs have a locking system but do not require keys. If you want to unlock the door, you can use a privacy emergency key instead. For passage knobs, you cannot lock them. The knob is purely for easy access to another room.
*To give a longer and more technical explanation: A 'Dummy Handle' is one handle or a pair of handles with no latching or locking function that are also a non-turning door lever or door knob. In other words Dummy Handles & Knobs do not turn to open but rather are used to push or pull a door open or shut.
A Security Lip strike plate reinforces door jambs and deters tampering or kick-ins for added strength and security.
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.
Door Security Guard Plates. Protect your doors from tampering and latch prying with steel security latch protector plates. These Door Security Guard Plates are perfect to cover the gap between the door and frame.
A sash door is a door that is partly constructed of glass and the door sash refers to the glass part of that door. The sash may include a single pane of glass or a collection of smaller panels. Sash doors are becoming increasingly popular for their ability to bring natural light and fresh air into closed off spaces.
