How do I secure my double-hung windows? Answered

I want to secure the bottom sash of my double-hung windows so I can lower the top sash for ventilation.


1) get two sided sticky tape.

2) get dowels

3) cut dowels to the length you want window to open.

4) put tape in track.

5) stick dowel to tape.

6) open window to dowel, it will not open more then the length you cut.
