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.
2. You will want to drill a hole through the inside sash and one-half to three-quarters of the way through the outside sash. See figure A. Measure this distance(depth). 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.
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.
