Your cart is empty. Constructed by zinc die-cast extruded aluminum, these Shop Square Sliding Window and Door Locks feature a thumb screw that provides a tool-free way to securely lock down a vertical or horizontal sliding window, even in a venting position.
Easy to install and use, place the lock on one of the sliding doors tracks; the outer track is usually the easiest, and use the twin screw-locks to create a tight grip, effectively locking the window or door in the exact position you would like it in.
Designed to be used with horizontal and vertical sliding windows and sliding doors alike, window vice locks have long been the preferred choice of homeowners looking for added security. Whether you are looking for a way to keep intruders out of your home or office or want a way to keep your children and pets from wandering off, track locks are the hassle-free way to achieve peace of mind.
Shop Square Window Locks work with tracks up to 3/16 inches wide. For added security, try using a lock on both the top and bottom tracks for a horizontal frame or the right and left sides when locking a vertical window frame.
Windows locks are beneficial when securing a window fan or AC unit or opening the window "just a crack" for ventilation. The reason for this is that you can effectively lock the window in the precise position that prevents the window from opening any further, securing both your home and the ac unit.
Please note: As a rule, window screw locks are designed to work with sturdy metal frames. Using them on thin edges, such as a delicate vinyl track, may damage the structure or allow the window to slide with pressure.
Requires 28-36mm Clearance for Lock Screws.

Not the best quality. I believed it would work better than my old windows stoppers , but they are much worse. Easy to open windows, doesn’t really fit the windows. Will buy another one

This is exactly what I was looking for. It's perfect, works extremely well and very easy to install. I will definitely buy more for my other push up windows. Gives me great peace of mind.

I bought these to put on every window in my house. They lock in really well so you don't have to worry about them falling out. I have bought these multiple times. Used them in my old house with regular windows and put 1 on each. In my new house the windows are larger so I like to put one on each side of the window. They are small but sturdy, and very easy to install. They are also simple to take off if you want to continue using the window.
