All About Internal Door Latch Types

Whether you’re constructing a new home or refurbishing an existing one, internal door latch types are an important factor to consider. Picking a suitable type of latch for your door can make all the difference in terms of both security and convenience. Let's take a look at some common types of internal door latches, so you can decide which one is best for your needs.

Mortise Locks

The mortise lock is a great choice if you’re looking for enhanced security. This type of lock is installed into the door itself and requires a key to open as it locks from both sides. Mortise locks are often used on main entrance doors, due to their strength and robustness. However, they can be quite bulky and require a lot of maintenance to keep them working properly.

Deadbolt Locks

Deadbolts are another popular choice when it comes to securing internal doors. They provide added protection against forced entry and come in various styles, including single-cylinder deadbolts that require a key from the outside but have no lock on the inside, as well as double-cylinder deadbolts that require keys for entry from both sides of the door. Deadbolts are usually more secure than other types of locks, but they can be difficult to install and may require professional help if you get stuck.

Privacy Lever Lock Sets

Privacy lever lock sets are great for bedrooms and bathroom door lock types where you want extra security but don't necessarily need something as heavy-duty as a deadbolt lock. These types of locks feature an interior lever handle and an exterior thumb turn knob that can be unlocked from outside via a keyhole or code padlock system. Privacy lever locksets also come with additional features such as passage knobs or dummy knobs that provide extra convenience without sacrificing any security features.

Lever Handles

If you're looking for something more decorative than traditional locks, lever handles may be the perfect option for you. Lever handles come in many different shapes and sizes, so you can choose one that complements your interior design style perfectly. While lever handles don't provide as much security as other options, they do offer convenience since they don't require keys or any additional hardware to operate them. As a bonus, they're also very easy to install.

Labeled Key Latch

The labeled key latch is similar to the lever handle latch but has an added feature a small label plate near the keyhole that houses a numbered code that is used to open the lock. This makes it perfect for shared spaces such as apartments or condominiums, where multiple people need access to one space without needing their keys or access codes. The labeled key latch is highly secure and can be customized to fit any specific needs or requirements.

Spring Latch Locks

Spring latch locks are another popular type of internal door latch that is usually found on sliding glass patio doors or windows. They have two parts the strike plate and the bolt which work together to create a secure closure when locked. The strike plate is mounted onto the edge of the frame and helps keep the bolt in place when it’s not being used. while the bolt slides into place when it’s turned clockwise or counterclockwise depending on whether you want to open or close it. This type of lock can be opened from either side with no need for a key or other tool, making it an ideal solution for interior doors where you may want quick access without having to fumble around for keys or codes.
