Are you endangering yourself with flimsy sliding door security hardware and window security? Here are just two examples of many thousands annually of why you want to fortify them:A woman heard the doorbell ring in her Camarillo CA home, but no one was at the door when she went to answer. Then she noticed that her rear sliding door was open and turned to see a man in her kitchen threatening her with a knife.
In Westboro MA, an intruder lifted a locked sliding door off the track of an apartment, entered, found a sleeping woman and raped her.
Sliding windows and doors (also known as sliding glass doors, patio doors, wall doors, or arcadia doors) usually have flimsy locks and frames that can be forced open or pried away. Reinforce them with one or more of the following:
1. Laying a sawn-off broom-handle (or 5/8-inch wooden dowel) in the
indoor bottom track prevents the door or window from opening. Lay it in the
innermost track to help prevent it from being lifted out with a coat
hanger from outdoors.
2. The frame attaches to the wall-frame with rather short screws. Replace the original screws with 4-inch screws.
3. Insert a few extra screws partway into the upper track – just
far enough in to allow the door to slide back and forth, but with
enough screw protruding downward to prevent the door from being lifted
out of the track.
4. Close the door, drill several small holes through the inner
panel (where the panels overlap) and halfway into the outer panel, then
slip a nail into each hole. Slant the holes downward so the nails won’t
fall out if jostled.
5. Most patio-doors have tempered glass (3-7 times
stronger than sheet glass) that resists a glass-cutter or bludgeon - but are still vulnerable. It's a good idea to add a home alarm system or DIY alarm .
The above also applies to side-to-side sliding home window security.
