Burglar Proof Your Home – Tip 5
Burglar Proof Your Home
Tip #5: Secure windows and sliding doors.
Many sliding doors can be popped off the frame, even when locked. Prevent this by placing a strong steel bar or two-by-four in the back groove, which prevents the door from sliding along the groove and opening. You can do the same with windows: Install a nail in the frame to prevent the window from opening more than a few inches.
