How do you cut off about one inch of the bottom of a metal door? What kind of tool do you need?
try a metal file and then sand the bottom smooth
you should not.... you will destroy the door. It is not a solidl door and the knob wont be at the right height...... Doors come in different sizes. return it and get the right size... if you cant return sell it ,and buy one that fits..
Use a jig- saw and blade for steel cutting.Measure out and draw a line on the length to be cut Alternative use a chisel and hammer,chiseled out as per drawn line
I wouldn't recommend you even try it. Most metal doors aren't solid inside it will ruin the door.
