Oh yes it is! Like I said before, you should place a bead of
stiff adhesive sealant (not caulk) under this threshold. You
can make sure that you hit the area you want the sealant to
seal by measuring and snapping a line. Your sealant should
stand up at least 3/8 to 1/2" and will seal against the bottom
of the metal. You can also put a bead of sealant on the
widest rib on the bottom of the door just before you stand it
up into the opening. Then, to be sure, put more sealant on
the outer lip of the threshold and seal it to the concrete
floor after the door is installed.
