I have a situation the same on two of the windows in the house and I can't seem to locate the part/parts that I may need. on the underside on one of the cranks the numbers found are 14 45054 the other is 16 45054. When I was cranking the windows closed, these parts detatched from the window. Im not sure if the crank is the part needing be replaced or the casement? Can anyone please help?
The name "BiltBest" is on the crank operator cover.
