A door knob that locks from both sides is called a double-sided deadbolt. This type of lock provides enhanced security for a door, as it can only be opened from either side with a key. Double-sided deadbolts are typically used for security doors, such as those leading to a garage, but can also be installed on interior doors for added privacy.
Unlike regular door knobs that can be locked from one side, double-sided deadbolts add an extra layer of protection and can be a deterrent to potential intruders.
What is a combined door knob?
A combined door knob is an integrated locking device that is both a door knob and a cylinder lock. This means that the same door handle is used to both open and close the door and provides the key operated security of a locking cylinder.
This is a convenient and popular solution for a range of buildings, but is particularly effective in public buildings, schools and universities, and commercial premises. The integrated design eliminates the need for manual locks or separate security measures such as padlocks, saving time, cost and providing greater convenience for users.
The combined system can be customised to suit the security needs of different premises, with a wide range of finish options including vandal-resistant models for extra protection. Combined door knobs are also available in a range of sizes to fit traditional British and continental door handles, or series of doors.
This combined door knob solution brings together the convenience of a door knob and the added security of a locking cylinder, creating a safe and secure environment.
What are the different types of doorknobs?
Each with its own benefits. Traditional cylindrical doorknobs are a classic round style, with a cylinder shape that can turn in a circular motion to open or close a door. These are the most common types of knobs and are usually used in residential homes.
Lever doorknobs allow the user to open or close the door by pushing down or pulling up on the handle. These are popular in commercial buildings and offer more leverage than a traditional doorknob. Ball-style doorknobs have a round knob with a ball at the end, which can be turned in either direction for opening and closing the door.
These are becoming more popular for residential homes, due to the ergonomic shape that is easy to grasp and the classic look. Privacy doorknobs are designed with a push button or turn tab inside the knob that allows the user to lock the door.
These are commonly used in bathrooms and bedrooms, as they provide extra privacy and security. With advancements in technology, you can now find electronic doorknobs that can be programmed to open using a code or using a keycard or smartphone.
These are commonly used in high-security areas, such as commercial buildings and government offices.
What is the difference between passage and dummy door knobs?
Passage door knobs are typically used in hallways or other spaces where accessibility is key. Depending on the style of passage door knob, they usually feature knobs or levers on either side of the door, allowing people to easily enter or exit the space without needing a key or unlocking mechanism.
Dummy door knobs, meanwhile, are often seen on closet or other doors that don’t require locking capabilities. Unlike passage door knobs, dummy door knobs only feature one half of the full knob mechanism and don’t have a system for locking or unlocking the door.
Instead, they are used to open the door manually and more often than not, they won’t require a key to do so. Dummy door knobs are usually used for aesthetic purposes, either to match other knobs in the home or to simply complete a look for a particular door, such as an ornate or decorative one.
Can you turn a regular door knob into a dummy door knob?
Yes, you can turn a regular door knob into a dummy door knob. This is done by simply replacing the existing door knob and latch with a dummy door knob and latch set. This can be done by removing the existing screws from the door plate and latch plate and taking out the old door knobs.
The dummy latch and door knob come as a set and typically have only one screw to secure them. Then the new dummy door knob and latch set is secured with the screw that was included. After careful installation, the old door knobs will no longer rotate, making them dummy door knobs.
Depending on the size of the door and the type of door knob, you may need additional fasteners to help secure the dummy door knob.
