Window Locks

Window Locks
Window locks can deter thieves from entering a home or commercial property via a window. These are simple devices designed to prevent intruders from forcing open a locked window. While no window lock is burglar-proof, they do offer substantially greater security than standard latches. Window locks are relatively inexpensive, effective and easy to install.

Consider Your Requirements

All window locks serve the same function, but they come with widely different catches and fittings for different types of windows. If you are planning to install security locks on your windows, you need to first consider the type of windows you have, and, most importantly, the functions they serve. Basement windows for example, serve mainly as an emergency exit. Your local fire codes may not even allow you to install a window lock on a basement window, and, if they do, you need to make sure that any lock you install on a basement window can be easily opened in an emergency.

Window locks are available in several different forms. Here are a few options that you might want to consider for your home.

Security Locks for Sliding Windows

These are easy to attach locks that are typically installed over the lower window track. Many such locks can be attached to the track with a single screw. When the key is turned one way, a metal stop slips over the window rail to prevent the window from opening. Some sliding window locks comprise of just a single key track stop bar that sits on the lower rail to stop the window from being forced open. Such locks can be positioned anywhere on the track. You can install a track stop to allow the window to be opened to a certain point for ventilation purposes.

Security Locks for Double Hung Windows

Double hung windows have two sashes, or windows that slide up vertically across from each other. Most such windows feature a crescent latch designed to prevent the windows from being opened. For added protection, you can pin the inner and outer windows together using a locking pin. Some locking pins require you to drill a hole in both the upper and lower sashes, while some drive in and out of the window pane using a special key. Locking pins basically prevent double hung windows from being opened beyond a certain point. Hinged wedge locks are another option for double hung windows. These are locks that can be installed anywhere on the window track. When the wedge is locked in place, it allows the window to be opened up to only that point on the track.

Locks for Basement Windows

In most cases, basement window locks comprise of a simple bolt that operates with a key. The lock is screwed to the window, while the metal cup, which receives the bolt, is secured to the window sill. The bolt is operated with a key, and cannot be slid out of the metal cup without it. Keyed turntable locks are also used sometimes to secure basement windows.

Casement Window Lock

Casements windows can have one or two panes. Security locks for such windows typically feature a revolving cam, which presses tightly against the sash when it is in a locked position. The locks are typically drilled into place at the point where the sashes meet each other, or where a sash meets the window sill.

Keyed security locks for windows can significantly bolster the security of a home, but care should to be taken to ensure that they keys are always accessible in an emergency. Window locks are a useful and inexpensive security addition, so long as care is taken to install them properly. However, keep in mind that window locks are no substitute for a full functional home security system with window alarms.
