I have old aluminum awning windows that open vertically when cranked. I want to completely remove the crank handle mechanisms on the windows I don't use and cover the openings, but I need a way to lock the windows. I purchased covers for the crank handle slots, but when I tried to remove the mechanism the window popped open. Do you know of any external locking mechanism for aluminum awning windows that could be applied so I can remove the crank mechanism, cover the slot and have the window remain closed and secure?
Sincerely, Matthew
