So i seen the videos, by Door Armor and seen the you tube vidoes of regular Joe's as well and it SEEMED simply to me. I have all the tools and such. Only thing i did not have was the 9/64 3" drill bit, and going to HD like always they dont have what you need. So if you are going to start get the drill bit way before, i bought what HD had which was 1/8 6 inch drill bit. I just bored out the hole more than normal, that took more time. Then when i took out the screws on the hinges on the my door they three were only 1/2 inch and one two inch on each hinge. So i replaced all the screws with 2 1/2 inch screws i had from a bath remodel. The hinge plates from door armor went on pretty smooth. I did drill the holes for the two small cover plates for the doors that was easy. NOW the long Jamb shield, i seen a video of a guy saying that if you can put 2 quarters together and slide them in the gap whith the door closed, you are golden. WELL not my door, so my door if you looked at it closed, the rop right has minimum gap and the bottom has a good gap, so the door was not installed correctly. SO i looked on the instructions for advice and low and behold it says to call Door Armor if i have problems installing...So i did, this was saturday, the door has some small parts off like strike plates parts, screws, tools, drills, etc all over and what do i get? Sorry we are closed on satruday!!!! WTF!!! No where does it say on the instructions they are only open during the week, so that was out, i looked on you tube for advice, but i cant stand the stupid music they play and tell you a story of how this one screwdriver was handed down from grandpa Jed long ago...GET TO THE POINT! So i gave up on that, time was ticking and i needed to get this door closed and secured. In the end i had to cut out part of the jam to make the Jam Shield have enough clearance that i could close the door. The screws by the way are real strudy but they strip REAL easy and that was frustrating, i even used a 15 to 16 impactm (not an impact wrench) on my drill to help but eventully i had to tighten them and then stripping happens, so that could be way better and maybe dont paint he actual groves on the screw? I did get it to close and all is good now but i didnt think it would take over 6 hours to add these parts with no help and just working through it. So far its installed and looks like the vidoes and such, and i can only hope that it works when needed.
