This StrikeMaster II is NOT for storm doors, it's designed to be used with entry doors, not storm doors
Yes, it can be installed on wood casings where the door is metal. If both the door and casing are metal, then you probably do not need it as the casing will not crack apart around the hinges or locks when kicked.
No. The instructions say to remove the strike plates.
Even if your door is scraping a little, like mine did, install it. Make sure the screws are fairly tight which pulls the frame enough to make installation a breeze. It works well! Excellent product, feel safer immediately.
Yes, this product will reinforce the door frame, but only on the section above and below the latch. It is designed to prevent the frame around the latch from cracking when kicked in at the weak point of the latch.
It may. Mine was very tight. I ended up splitting the twi pieces and only using one. But the door works just fine
You will have to measure your door frame and decide based on the measurements of the frame. The door jam re-enforcement metal piece that attaches to the frame is 4' long, 1 7/8" wide and has a 5/16" lip which fits a residential doorframe perfectly. If the door on your mobile home is thinner than a standard residential entry door, door jam may not be deep enough to install the StrikeMaster II. Also, the screws that are used to install the re-enforcement piece are 2 1/2" long. You have to verify that when you put these screws in that they are going into the door jam and the wood behind it, and are not going to hit something in the mobile home wall such as wiring. Also note that when installed, the metal piece occupies 1/8" between the door jam and the door. While this might not seem like much, it may prevent the door from closing. My front door which has sagged some over the decades barely closes with the StrikeMaster II installed (I had to beat on my door hinges with a sledge hammer to get them to not sag as much so my door could close). Good luck! I hope it fits and gives you some security!.
I don't believe this would work for inner doors that are hollow or flimsy in any way. If it is a solid sturdy wood or metal or fiberglass door, this would work. Of course, it is visible along the inside edge of the door.
