This door fit my need pretty good.  The old door had water damage and I prepped this door with good pain before mounting.  I had to sand a little off one edge because the door opening was not square and it was easy.  Since this was for a water heater room, I drilled holes in the panels and covered with screened vents from a local hardware store.  I also bought the water heater in the room, but can't review it because it isn't listed in my purchases for some reason.  It is basically the same water heater I took out that was 12 years old.  I had to add an expansion tank that my old one didn't have. Without it, the heater was forcing water our the overflow valve when heating.  It's been in a couple months and is working fine.
