Types of Deadlocks for Doors
Deadlocks with hook bolts are used on aluminum sliding narrow stile storefront doors to enhance security and strength of the lock. They have keys on both sides, allowing for greater flexibility.
To accurately measure a new lock, first determine the door's depth (or backset). This is the distance between the edge of the front door and the center of latch hole.
Tubular Latch
The tubular latch is the most popular door latch. It's easy and simple to install, making it a favorite of Joiners and DIY enthusiasts alike. It's also available in a wide variety of sizes, shapes and levels to match any door handle style.
A tubular latch is an rectangular steel casing that has the latch bolt as well as a latch follower with springs (also called a striker). When you open the door the latch retracts to allow you to lock and close it. When you close the doors the latch bolt swivels back and grabs the edge of frame to hold the door closed.
You'll need to decide on the size of the door's latch before you put it in place. Many people believe that one metre from the floor is the ideal height to position a latch and door handle. However, this isn't the case. When it comes to door knobs the latch should be located in the middle of the rail - this is where the bulk of the weight is shifted when you open and close the door.
Mark the position of the hole in the door. Then, strike the plate with a pen once you've decided the location where the latch should go. Drill pilot holes to secure the plate. After you've made these holes, use a countersink bit to ensure that the back of the plate sits flush with the door when it's screwed.
If you want a heavier-duty alternative to the standard tubular latch, you should consider choosing a double sprung variant. This has an additional spring for the tongue movement, resulting in a more smooth closure when you open and close the door. It also has a strong-action spring on the spindle follower, which ensures that levers or doorknobs return to their horizontal positions following every use.
After you have installed the latch on the door, you will require a strike plate in the frame. The strike plate is the part that sits in the gap that is left by the latch when it's closed. To make this happen, mark where you want the strike plate sit on the frame section that is surrounding it. Use your knife to cut a square for the plate and then remove it.
Cylindrical Latch
Cylindrical locks are often employed on doors for interior use. They are used in offices and homes, and can be found in numerous applications. They are similar to mortise locks but they are easier and quicker to install. They do not require that a "mortise" or pocket be cut into the door's frame like mortise locks do. van hook locks fitted or bore is cut into the frame of the door, and they are inserted into that. They come in a variety of grades and are compatible with both knobs and levers to open and close the door.
The main distinction between mortise and cylinder locks is that only a specific key can unlock these types of locks. This is because they employ pins that are different in height inside the cylinder, as well as springs to hold the pins in the right position. When van hook locks fitted is used into the cylinder, the pins align with each other and the cylinder rotates. This allows the latch bolts to retract which allows the door to be opened.
If the wrong key is used, the pins aren't aligned correctly, and they stop the piston from moving. This is why it's crucial to use only the right key whenever you want to enter your home or office.
The cylinder is positioned inside the door's body and is connected to the operating trim with either a half-round or square extension. The cylinder also has small notches on its sides that are designed to align with the key notches when the right key is put in. When the cylinder moves it will also move the latch bolt with it.
A strike plate is a plate that attaches to the door frame and captures the bolt of the latch that is projected to the lock. The strike plate is typically made of heavy-gauge steel and is attached to the door frame using screws. It also has a strike opening which the latch bolt of the lock engages.
Use the right tools to remove the handle or knob of the lock that was previously used and the latch bolt. After the old hardware has been removed, mark the location of the new latch bolt and strike opening on the door and frame. It's a good idea test your lock's operation by pressing the latch bolt or strike plate using your finger. If the strike plate or latch bolt is damaged or fails to work properly, you should look into replacing the bolts and strike plates.
Key-Locked Latch
This kind of lock is controlled by a key on the outside, and a knob/lever on the inside. It is used in places where unauthorized use of the lock is not an issue, such as office doors. This kind locks allows the lever on the outside to be locked or unlocked while the interior knob/lever remains free for immediate exit. The key is required only to retract the latchbolt when the door is shut.
The pins of a key-lock are oriented and lined up along a line known as the shear line. These pins align with the shearline when the key that is needed is inserted into the lock. The plug is then turned to open the latchbolt. If you've had a key that fits perfectly into a lock but still won't open it could be due to one of the pins isn't aligned with the shear line.
Face plates are also utilized on a few locks. They can be decorative or add strength and protection to the locking mechanism. These plates are commonly found on mortice locks, rim locks, and locks with reversed springs.
There is also a strike plate, that is typically connected to the door frame and jamb and is fitted with a hole to guide the bolt from the cylinder to the lock. This is often employed with deadbolts to offer added security.
Then, there's the cylinder, which is a series of pins that align with the key's axis to stop it from turning. It can be difficult to choose a cylinder of good quality without the proper tools and understanding. To lock a door it is necessary to turn the key turned in the same direction as the door is opened. For instance, if the door opens right-handed the key needs to be turned clockwise to lock it. To unlock, turn the key counterclockwise. This is different from other locks which require you to turn the key in the opposite direction to the way the door opens as in for instance a Chubb lock.
Keyless Latch
With a keyless latch you can lock and unlock your doors without a traditional key. These locks can be controlled via a smartphone app or an access code. Some models come with a hidden security camera. Take into consideration your security needs and compatibility with existing hardware and doors when you select a keyless lock. van hook lock fitting require special door preparation or modifications, so check the manufacturer's specifications and installation instructions prior to installing.
Many companies are working on smart locks that replace traditional locks with keys and offer additional security features. They are more robust and can be locked through fingerprint, code or facial recognition. Some smart locks also have tamper-proof features and can detect when a door has been opened using a key that is not authorized or force.
One company, known as Latch, has developed an attractive, high-tech lock that works like other smart locks. Its main market is realty companies which manage apartment blocks. The lock can be opened with a key, passcode or a mobile phone, and renters are able to let in cleaners, dog walkers or guests from out of town with temporary codes. The company claims that this will eliminate the need for tenants losing their keys, and will reduce maintenance costs since there's no need to replace locks if the tenant moves out.
The Latch lock isn't accessible to the public at this point however it may find a place in condos or apartments with large spaces. It's currently being tested in a handful of places, and the company plans to roll out more units in the coming year. The cost is about the same as a standard lock, and the company also offers an affordable price and low software fees.
You can change the shortcuts at any time by using the Latch App. To do this, start the app and then select the menu at the top left-hand corner of the screen. Select 'Widgets,' and then select the doors you wish to display as shortcuts. You can see the access history of your doors on the Latch App after you've configured them.
