Window handles, often referred to as window cranks, can be found on new windows in some homes but are most common in older ones, particularly those built in the 1950s. The window handle is a simple device that, when turned, opens the window. Give it a spin in the other direction and your window closes. After years of usage you’ll probably notice that the handle stops working. This is likely because the gears have stripped away at the handle. You can fix broken handles in a few easy steps.
Remove the old handle from its base to expose the gear underneath. This might be as simple as pulling it right off, though some models might require the use of a screwdriver.
Place the new window handle on top of the gear and fasten it into position.
