Do Your Double-Hung Windows Provide An Easy Entry To Your Home?

Double hung window pic Window pinning can be an effective way of securing double-hung windows (and some sliding windows). We run into a lot of double-hung windows, usually in older homes, that could use this type of protection. Many have locks/latches that are broken or the two window sections don’t line up preventing the window from being secured.

Best Application: On older double-hung windows that have wooden frames and require extra protection. Not recommended for use on vinyl windows – it may even void their warranty.

NOTE: using this window pinning procedure still allows someone in the home to escape through the window should that become necessary. Never use any method of securing windows that would violate any codes or prevent someone from escaping in an emergency situation.

Tools Needed: Hand or electric drill; 5/32” drill bit; ruler or tape measure. Each window will also require two 16-penny nails.


1. Close the window and, if possible, secure it using the existing lock/latch. If you can't secure the window, make sure both the upper and lower sections are shut tight as they must overlap as much as possible.

Once you have the depth to drill, you may want to place a piece of masking tape on the drill bit at the same distance. This can be your guide for how deep to drill.



3. Starting on the left side, carefully drill the hole at a slightly downward angle but no deeper than the depth you measured in step 2 (or the start of the masking tape on the drill bit).

4. Repeat Step 3 on the right side and insert a 16-penny nail into each hole.

Test the new security by unlocking the latch and trying to open the window with just the nails in place.

NOTE: You may want to cut off the tips of the nails so that just the nail heads are visible and sticking out. Use a bolt cutters or hack saw to shorten them.

If you want the option of leaving one or more windows WindowVentPicopen (4” to 6”) and still remain secure, you may drill two additional holes as follows:

Open the window the desired height (but no more than 6”); Using the existing holes on the inside sash, drill a second set of holes one-half to three-quarters of the way through the outside sash; Insert the 16-penny nails through the inner sash and into these “ventilation” holes and test by trying to open the window wider.

Double Hung Window Locks Wood Window Locks-For Those Vulnerable Double-Hung Windows

These window locks are the best ones I have sold and installed for securing wood double-hung windows. They are intended to be used as a more permanent security solution for vulnerable windows. As such, they are not for use on vulnerable windows that are designated as escape routes in case of fire or other life threatening events.

You won't find these locks in stores. In fact they can't be found anywhere as they are no longer being made by this company. I have just two cards left - each of which can secure six small windows or three large ones. Priced at $7.95 per card plus shipping.

If you are interested in one or both cards, contact me. I can send you installation instructions if you wish. But the first Email I receive from a committed buyer will get the locks.  A PayPal invoice will be sent to the buyer and this offer will be taken down. All sales are final.
