How To Tell The Good And Bad About Hook Locks For Doors
Types of Deadlocks for Doors

Hook bolt deadlocks are installed on sliding narrow stile aluminum storefront doors to enhance security and strength of locks. These locks are double-keyed to give greater flexibility in access control.

To accurately measure for the new lock, first determine the door's depth (or backset). This is the distance from the edge of the door to the centre of the latch hole.

Tubular Latch

The tubular latch is the most sought-after type of door latch. It's simple to install and is popular with DIY enthusiasts and joiners alike. It is available in various sizes shapes, shapes, and levels that can be used to match any door handle style.

A tubular latch is an rectangular steel casing that has an latch bolt and an encased latch follower that is spring-loaded (also called a striker). When you open the door, the latch retracts to allow you to shut and lock it. When you shut the door, the latch bolt then springs back to catch on the edge of the frame and close the door.

When you're fitting a tubular latch, you'll need to decide how high you want the latch to be positioned on the door. Many people believe that a latch and handle should be positioned at a height of 1 centimeter above the floor. However, this is not always the case. When it comes to door knobs, the latch should be situated in the middle of the rail - this is where the majority of the weight is shifted when you open and close the door.

Note the location of the hole in the door and strike plate with a pencil once you have decided the location of the latch. Drill pilot holes to secure the plate. After drilling the pilot holes, you can use a countersink to make sure that the plate's back will sit flush with the door after it's screwed in place.

If you're looking for a stronger-duty option than the standard tubular latch, you should consider opting for a double-sprung model. The door will close much more smoothly when you use this latch because it comes with an additional spring that moves the tongue. It also has a strong-action spring on the spindle follower, which ensures that doorknobs and levers return to their horizontal positions following each use.

Once you've fitted the latch to the door, you'll need install a strike plate onto the frame. The strike plate is the part that is placed in the gap left by the latch when it is closed. Mark the location where you'd like to put the strike plate on the frame surrounding it. Use your knife to cut a square for the plate and then take it off.

Cylindrical Latch

Cylindrical locks are often employed on doors for interior use. They can be used in offices and homes and are extremely versatile in terms of their applications. They are like mortise locks but they are easier and quicker to install. They do not require a "mortise" or pocket be cut into the frame of the door as mortise locks do. The hole or bore is cut into the face of the door, and they are then inserted into the door. These locks come in different sizes and can be used with both knobs and levers to shut and open the door.

The primary difference between mortise and cylinder locks is that the latter locks can only be opened using the right type of key. This is because they employ pins of different heights inside the cylinder, as well as springs to keep the pins in place. When the correct key is inserted, the pins align with each other and the cylinder can rotate. This allows the latch bolts to retract and allow the door to be opened.

If the wrong key is used, the pins aren't aligned correctly, which stops the cylinder moving. It is crucial to use the correct key to gain access to your home or office.

The cylinder is positioned within the door's body and is connected to the operating trim using either a half-round or square extension. There are also small notches carved from the cylinder's sides that match with key notches, and they are designed to line up when the correct key is put in. Once the cylinder has been moved by the latch bolt, it will follow.

A strike plate is an attached metal plate that is used to catch the bolt of the lock that is projected. The strike plate is generally made of heavy steel and fixed to the door frame with screws. It also has an opening for the latch bolt to fit into.

When replacing a cylindrical lock ensure that you make use of the appropriate tools to remove the handle of the old lock or knob and latch bolt. Mark the location of the new latch bolt and strike on the door and frame after taking off the old hardware. Once the latch bolt and strike plate are in place, it's a good idea to test the operation of the lock by putting it against it with your finger. If the latch bolt or strike plate is damaged or doesn't operate correctly, you should think about replacing them.

Key-Locked Latch

This kind of lock is controlled by a key that is inserted from the outside, and a lever or knob on the inside. It is typically used in areas in which the unauthorized use of the lock is not an issue, such as office doors. This type locks allows the lever on the outside to be locked or unlocked while the inside knob/lever is open to be used for immediate exit. The key is needed only to retract the latchbolt after the door has been shut.

The pins of a key-lock are aligned and pointed towards a line known as the shearline. These pins are aligned with the shearline when the correct key is put into the lock. The plug can then be turned to release latchbolt. If you've ever had a lock that was perfectly aligned, but the key could not be opened it is possible that one of the pins might be not aligned with the shearline.

Face plates are also utilized on some locks. They are decorative or can add strength and security to the locking mechanism. It is common to see these plates on mortice locks as well as rim locks that have reversed spring bolts.

There is also a strike plate that is typically attached to the door frame and jamb and has a hole that guides the bolt from the cylinder to the lock. This is often used in conjunction with deadbolts for additional security.

The cylinder is the final component, and it has pins that are aligned with the key's tip to prevent it from spinning. It can be difficult to choose a cylinder of good quality without the proper tools and understanding. To lock the front door, turn the key in the same direction that the door opens. If the door opens using the right hand, for example the key needs to be turned clockwise to lock the door. To unlock, the key must be turned counterclockwise.

Some models come with cameras hidden in the door. When choosing a keyless latch be sure to consider your security requirements and compatibility with your doors and hardware. Review the manufacturer's instructions and specifications before installing. Certain keyless locks could require special door modifications or preparations.
