Window Pins Security: The $5 Hack That Stops Intruders Cold

You don't need a monthly subscription to secure your double-hung windows. You just need a drill and a steel pin.

In an age of AI cameras and Wi-Fi smart locks, we tend to overcomplicate home security. But if you ask a veteran locksmith or a retired burglar, they will tell you the same thing: Mechanical failure is the only thing that physically stops an entry.

Most standard window latches (the half-moon locks in the center) are flimsy. A crowbar can pop them in seconds. Window Pins, however, physically fuse the bottom sash to the top sash (or the frame), making it mechanically impossible to slide the window open without breaking the entire unit.

The Concept: "Pinning the Sash"

By drilling a hole through the inner sash and halfway into the outer sash, inserting a pin locks them together. Gravity keeps the pin in. Physics keeps the burglar out.

How to Install Window Security Pins (10 Min)

This works for wood and vinyl double-hung windows (windows that slide up and down).

Step 1: The Purchase

Go to the hardware store. Buy 1/4 inch steel eyebolts or specific "window security pins." Do not use nails (too thin, can bend).

Step 2: The Drill Angle

Close the window and lock it. Drill a hole at a slight downward angle through the top corners of the bottom sash. Stop when you penetrate about 3/4 of the way into the outer sash. DO NOT drill through the glass!

Step 3: The "Vent" Position (Optional)

Open the window 4 inches (safe ventilation height). Drill a second set of receiving holes in the outer sash track. Now you can pin the window in a slightly open position for fresh air, and it still can't be opened further.

Why Do It?

Standard Latch
Fails under pry-bar pressure
Window Pin
Shear strength > 1,000 lbs
Installation
Requires drilling holes (Permanent)

Simple. Strong. Smart.

This is the ultimate low-cost, high-reward project for a Saturday afternoon. Just make sure you keep the pins easily accessible (or tied to a small chain) for fire egress.
