hi, go do a search for mila hardware on internet flag hinges. it shows the product on there and how to fit them . so would guess fitting is reverse of removal .
i would assume its just a matter of having the door half open , then from what i can see take out bottom weather caps of the hinge . then pull the door up and off after knocking out the centres of the hinges??
hope that helps . i arnt sure mind .........
window repair boys best bet for advise........
