11 Different Types of Window Locks

Windows are essential to our homes and businesses, providing natural light, ventilation, and a view of the outdoors. However, they can also be vulnerable to intrusion if not secured properly.

Fortunately, there are some excellent window-locking solutions to keep your property secure and provide peace of mind. This article will explore the different types of window locks available, helping you choose the one that best meets your needs.

What Are the Different Lock Grades?

According to the American National Standard Institute, locks come in various grades, ranging from the lowest security to the highest. The grade of a window lock represents the overall strength and quality of the lock, as well as its ability to resist forced entry.

1. Grade 1 Locks

Grade 1 locks offer the highest level of security available for window locks. These locks are designed to meet the most stringent standards for installation and use. Grade 1 locks are typically made of high-grade steel and feature drill-resistant components.

Grade 1 locks often come with additional features such as tamper-resistant screws, padlocks, or lag screws. Grade 1 locks are often used in commercial buildings and other places where extra security is needed.

2. Grade 2 Locks

When it comes to window locks, grade 2 locks are the most popular choice. Often referred to as “standard” or “normal security,” these locks are created to provide an adequate level of security. Grade 2 window locks typically feature a keyed deadbolt, operated by either a key or a thumb turn.

The lock itself consists of a metal cam in the frame, which fits into either a mortise style or surface-mounted strike plate. This type of lock provides a moderate level of security but is also relatively easy to install and maintain, making it a great option for professionals and homeowners alike.

3. Grade 3 Locks

Grade 3 window locks are typically made from lighter-weight materials and offer a lower level of security than grades 1 and 2. These locks are typically used in residential homes, where they can provide adequate protection from burglars. They are typically installed in sliding windows, casement windows, and double-hung windows.

Grade 3 locks can also be used on awning windows or hopper windows. Grade 3 locks usually feature a keyed deadbolt or an interior thumb turn.

What Are the Different Types of Window Locks?

Window locks come in various types, each providing varying levels of security and convenience.

1. Bolt Lock

Bolt locks are one of the most popular types of window locks and offer a high level of security. They usually feature a large cylinder in the center of the window frame that fits into a matching cylinder outside the window frame.

This locking mechanism is known as a “deadbolt” because it requires two separate movements to open the window; one on the inside and one on the outside.

Deadbolts are often used in combination with other types of locks, such as keyed locks or lever handles, to add even more security. They are also typically installed with window-specific hardware, such as security bars and window guards, to further protect the home.

2. Keyed Window Locks

Keyed window locks have been around for centuries and are still the most common type used today. These locks require a physical key to open and close, making them ideal for home and business use. Keyed locks can be installed in various ways, including deadbolts and mortise locks.

Deadbolts are typically mounted directly onto the window frame and secured with a key, while mortise locks are embedded into the window frame itself. Keyed locks provide an extra layer of security and can be used to secure windows on the ground floor and those higher up.

3. Padlocks

Padlocks are another popular window lock used for home or business applications. Padlocks are usually attached to the window frame and secured with a combination or key. They provide additional security and are an inexpensive solution for those looking for a quick and easy locking system.

Padlocks come in various shapes, sizes, and colors, allowing you to choose one that best fits your needs.

4. Sliding Window Locks

Sliding window locks are an ideal solution for secure sliding windows. These locks are designed to fit inside the window track and prevent the window from being forced open from the outside.

Sliding window locks are easy to install and can be adjusted for different window sizes. They also provide an extra layer of protection against intruders, making them a great choice for homes and businesses.

5. Sash Locks

Sash locks are designed to provide security for windows that open vertically. These locks are typically mounted at the top and bottom of the window, preventing it from being opened.

The window sash locks are available in various styles, including keyed sash locks and combination locks. They provide an extra layer of security for windows located on the ground floor or higher up.

6. Casement Window Locks

Casement window locks are designed for windows that open outward, also known as casement windows. Casement latches come in several different styles and sizes, providing you with plenty of choices to fit your window’s needs.

Most latches are made of steel, and some are available in brass or other metal finishes. Casement latches can be mounted on the window frame using screws or lag screws and may require drilling into the window frame to install.

7. Swivel Action Lock

A swivel action lock is a type of window lock designed to fit over the window sash to secure it in place. This type of lock operates by a swivel action engaged when the window is closed and locked. When engaged, the swivel action makes it impossible for anyone to open the window from outside.

Swivel action locks are generally easy to install and are available in a variety of materials, allowing you to customize the installation process to your specific window needs.

8. Window Pin Lock

A window pin lock is a great option for those looking to secure their windows without needing a key. This type of lock uses a locking pin inserted through the window frame, making it difficult for an intruder to open the window. The pin can be removed when the homeowner wants to open the window, making it a practical and secure option.

9. Snib Lock

A snib lock is a simple locking mechanism that uses a snib, or small metal latch, to secure the window in place. It can lock single or double-hung windows and requires a key to open. This lock is common in older homes because it is inexpensive and easy to install and is often found in combination with a padlock or lever handle.

Snib locks provide basic security, as they are easy to open from the outside with a thin object such as a wire hanger or metal ruler.

10. Chain Lock

Chain locks are designed for windows that open outward, such as an awning or a single-hung window. This type of window lock will stop the window from being opened more than a few inches, and no matter how hard the window is pushed, it will not budge. Chain locks are easy to install and come in various finishes, such as brass or white.

11. Self-Locking Smart Locks

Smart locks offer an extra layer of security for any window. Smart locks can be controlled using a smartphone or other window-opening control devices to self-lock and unlock when the homeowner needs it.

Smart locks work by detecting when a window is opened and can self-lock when closed. This type of lock is perfect for any homeowner who wants peace of mind knowing their windows are securely locked.

What to Consider When Choosing a Window Lock

When selecting a window lock, it is important to consider the type of windows in your home and the security needs. Different types of locks offer different levels of security, so it is important to choose a lock that best meets your needs.

Also, consider the durability and finish of the lock, as well as how easy it is to install. By knowing what type of windows you have and what level of security you need, you can easily choose the right window lock for your home.

Tips for Window Lock Installation

When installing a window lock, it is important to use the proper tools and materials. Depending on the type of lock you are installing, you may need a screwdriver, chisel, or drill.

Many window locks are secured with screws, so it is important to ensure that the screws you use have the right size and length for the job. Use the right type of screw depending on the material used in your window frame. Additionally, some locks are installed using a chisel or drill.

Once the lock is secure and properly installed, test it to ensure it works correctly. It should be easy to open and close the window using the lock. If it is difficult to lock or unlock, you may need to re-adjust or even reinstall the lock.

Final Thoughts

Window locks are an essential part of home security. By understanding the different types of window locks and installing them correctly, you can ensure your windows are securely locked and that your home is safe.

Whether you are looking for a simple pin lock or a sophisticated smart lock, there is an option available to suit your needs. So make sure you choose the right lock for your windows and keep your home safe.
