A lockset (alternatively lock set) is the hardware and components that make up the locking or latching mechanism that can usually be found on a door or other hinged object but can also include sliding doors and dividers.
Keyed or entrance function:
A keyed entrance function would generally be used on a front or back door, or any exterior door. It has a keyed cylinder on the outside where you would need to use a key to unlock and lock. The keyed functions have a turn button on the inside, similar to the privacy lock.
1. Deadbolt Locks. Deadbolt locks are a common, effective and cost efficient way to secure most external doors. The locking mechanism revolves around a cylinder that runs directly through your door and has a keyhole on the outside.
The Bolt: Also called the latch, the bolt engages the inside of the door. There is a piece of metal that extends from the door into the frame itself. This bolt is used to hold it closed.
There are three main types of door handles: lever handles, pull handles and door knobs.
Both door handles and doorknobs help control the opening or closing of doors. The key differences between the two will depend on the shape, convenience, and the home's overall style. Door handles look like levers while doorknobs have a round shape. Door handles require less effort when opening compared with doorknobs.
The most common are 2 3/8 inches and 2 3/4 inches, but some hardware can fit multiple backsets. Make sure the hardware you select fits your door. For more help, see Determine the Backset of Your Door.
To keep the latch bolt from being push-retractable once the door is closed, a second mechanism is incorporated into the latching mechanism—called a deadlocking plunger (the entire mechanism sometimes called a deadlock latch), as shown in Figure 3.
In the United States, there are two common backsets for residential door locks: 2 3/8 inches and 2 3/4 inches. Pack your locks with a 2-3/8-inch or 2-3/4-inch latch, depending on which backset you specify. Dummy sets have no latch and are surface-mounted so you can install a dummy set wherever you choose on the door.
The strike plate is placed on the door jamb where the hole for the bolt of the door and the bolt meet. It is a small metal plate that is screwed to the door jamb.
Although there are many types of locks, the four most common are padlocks, deadbolts, knob locks, and levers.
A classroom function deadbolt prevents an unauthorized person from projecting the deadbolt to secure a room without permission, but provides for safe egress by allowing the thumbturn to retract the deadbolt if an occupant is accidentally locked inside the room by someone projecting the bolt with a key.
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.
The main parts of a door lock are the cylinder, bolt, box and strike plate.
Can these internal handles be used on a front door or exterior door? You can use them on an exterior door, and many people do, but the longevity of the handle with respect to resistance to weathering is not as strong as needed.
Cylindrical Lever Locks
Cylindrical lever locksets are the most commonly used lock type and are offered in a range of features, functions, grades, styles and finishes no matter how demanding the application.
The backset is the distance from the edge of the door to the spindle mechanism on the latch. Usually a 63mm case measurement will have a 44mm backset and a 76mm case measurement will have a 65mm backset. The backset you choose is where your door knobs will sit on the door (where the spindle goes through).
Basically, you cannot re-key the lock from Schlage to Kwikset, but you can change the lock cylinder from Schlage to Kwikset.
You have three different latch face plate options: *Helpful Hints: Round Corner - The corners of the faceplate are rounded (1/4" radius latch). Square Corner - The corners of the faceplate are square. Drive-In - The latch is designed to be used without a faceplate.
A deadlatch is a type of lock that can automatically lock itself without needing a key or a knob to move the blot in place. Essentially, it contains its own security latch which can immediately lock itself as soon as you close your door. You will commonly find deadlatches on front doors that do not have a handle.
A deadlatch is a locking mechanism that locks automatically without having to turn a knob or use a key. It rests against a metal strike plate mounted on a door frame. The deadlatch works by using a bolt to block the door from opening, giving your door extra security.
Measure from the edge of the door to the centre of the door knob or handle. The industry standards are usually either 44mm / 57mm / 82mm / 107mm / 130mm. Ideally you will try and choose the backset measurement that sites the door handle in the middle of the door stile.
To have the door function properly, you will have to make sure that the door knob you buy is the correct size for your door. The standard size for a door knob diameter is either 2 3/8 inches or 2 3/4 inches and these knobs will usually fit doors that are anywhere between 1 3/8 inches to 1 3/4 inches thick.
You'll need to know the bore hole's diameter to get the right sized knob. Measure across the circular hole at its widest point, i.e. start at the bottom of the hole and pull the tape until you hit the top of the hole. There's your diameter. Write down the number of inches that you see on a small notepad for reference.
