Window Sash Lock
As any homeowner knows, a window sash lock is a fundamental component of one’s residential structure. It provides security, privacy, and helps keep out drafts or external noise. But how much do you really know about it? In this article, we are going to break down everything from the definition to the function of a window sash lock through our eyes as a company providing part identification services. You will come away with not just a basic understanding, but a comprehensive knowledge of this critical component.
What is a Window Sash Lock?
A window sash lock is a device consisting of two pieces that attach to the movable part, called the sash, of a double-hung window. One part is a catch that secures the window to the other part which is the “keeper” that’s typically screwed into the window frame. The window sash lock integrates into a sash, allowing it to move up and down so that the lock falls into place, effectively “locking” the window into place.
The sash lock is the primary locking mechanism of a window. Some sash locks include keyed locking functions, while others are available as a ‘thumbturn’ or knob release style lock. While sash locks are usually fabrications of metal alloys, some may come with a plastic case.
The Function of a Window Sash Lock
The function of a window sash lock is straightforward. It serves two primary purposes: to keep the window shut for security reasons and to keep the sash in the correct position to prevent drafts and to ensure it hangs correctly. If a window sash lock is not working appropriately, the window will not stay shut or have the proper tension, allowing it to move around easily, resulting in unwanted noises, draftiness or water ingress during rains. Moreover, a window sash lock is vital in preventing intruders from gaining access to your property, especially if you have windows that, if unlocked, can be accessed from outside.
In some cases, a sash lock may be redundant, given other mechanisms on the window. For instance, some windows have a cam lock or a multipoint locking system, offering a more extensive locking system that is more secure and harder to pick. However, regardless of whether a window has a multipoint locking system or a cam lock, sash locks remain essential as they secure the unlocked window’s sash from moving.
Repairing a Window Sash Lock
Window sash locks may malfunction even though they are fundamental pieces. The most common issue is a worn-out lock that no longer keeps the sash shut securely. Fortunately, some repairs can be carried out quickly and without the need for a replacement. For example, a poorly placed or bent keeper can often be repaired through alignment or bending it to properly engage the lock. A related issue might be one where the sash lock mechanism has failed and now has little to no spring tension rendering the lock ineffective at securing the sash. Often, this is due to the spring having worked itself loose or breaking from age and fatigue, and can often be replaced by an experienced technician without the need for a new sash lock.
Another problem that can arise is a lock that is difficult to operate due to debris such as dirt or grime that’s accumulated on the components, making it difficult for it to slide or operate smoothly. In some cases, cleaning the mechanism with a damp cloth or lubricating it can solve this problem. However, cleaning may not be easy, and a professional locksmith must undertake it safely and securely.
