WinLock Window Security Bar for Child Safety and Burglary Prevention

In this review the WinLock Window Security Bar is assessed as a simple, mechanical way to secure double hung windows that are held open for air conditioners or fans. The bottom line: it is best for homeowners and renters who want a visible, heavy duty deterrent and a removable solution that requires no tools to install. For anyone worried about a child falling out or a burglar exploiting an open sash, the WinLock provides a central steel interlock that holds the top and bottom sashes relative to one another and keeps the window from being pushed open.

Key Features

• Double hung protection: The bar secures both the top (outside) and bottom (inside) sash so the window cannot be opened from either side when installed, reducing entry risk.
• Solid steel construction: A steel connection gives visible, physical resistance that acts as a deterrent and feels sturdy to the touch.
• Adjustable length: The rod adjusts to fit openings from about 3 to 17 in so it can be tailored to common portable air conditioner and fan installations.
• No tools installation: Installation is quick and reversible - open the window, place the base, insert the rod, close and lock - useful for seasonal or temporary needs.
• Child safety and burglary prevention: Designed to stop a sash from moving, the bar helps prevent child falls and keeps a window appliance from creating an insecure opening.
• Visible deterrent: Its presence at the center of the window communicates added security to would-be intruders and during storms.

Who It's For

The WinLock is aimed at homeowners, renters and caretakers who use window air conditioners or fans and need a simple way to prevent the sash from being opened inward or outward. It suits anyone who prefers a mechanical, tool-free device that can be adjusted to a variety of sash thicknesses and left in place when a window must remain partly open for ventilation.

People who want an electronic lock, keyed deadbolt style integration with existing window hardware, or a permanently mounted reinforcement should look elsewhere. This device is a removable bar intended for sash isolation and visible deterrence rather than a complex locking system.

Pros & Cons

Pros

• Solid steel build gives a reassuring feel and long-term durability according to users.
• Easy, tool-free installation makes it practical for renters and seasonal use.
• Adjustable sizing covers many window and appliance setups, adding flexibility.
• Effective at keeping a window latched when using an AC or fan, providing peace of mind.

Cons

• One limitation is the need to measure sash thickness before ordering since different widths are available and returns are not accepted.
• The visible design can be removed if someone opens the top sash from outside, so it is not a replacement for fully reinforced window systems.

Frequently Asked Questions

Can this be used with a window air conditioner?
Yes. The bar is adjustable to isolate the sashes while an AC or fan holds the window open and helps prevent the appliance from creating an unsecured opening.

Is any special hardware or tools required to install?
No. Installation is tool-free: open the window, position the base, insert the rod, close and adjust to lock in place.

Will this prevent a determined intruder?
It is a visible, heavy duty deterrent that increases security, but it is not a substitute for a permanently reinforced window system and can be defeated if the top sash is opened from the outside.
