Replacing a hollow metal door in an existing hollow metal frame? Keep in mind one size does NOT fit all! Different manufacturers have their hinge and lock preps in their doors at different locations. So make sure to measure each hinge location from the door top (FDT) to the top of each hinge, and measure the lock FDT to the centerline. We have some handy forms with pictures for you to print at the link in this post that will make it easy for you.
