The StrikeMaster II Pro stops home invasions by preventing door kick-ins. FBI statistics show that the majority of home break-ins are caused by burglars kicking in the door. Unless extra reinforcement is taken to strengthen the door frame, a forced entry of kick-in burglary will split open the wooded door frame around the lock. StrikeMaster II Pro provides real protection. It's the easiest to install door jamb and hinge reinforcement product available. Its 4 ft. of customized steel turns soft wood door frame casing into solid steel. The StrikeMaster II Pro's patent pending double steel plate design along with extra long screws, bite into the wall studs surrounding the door frame reinforcing the casing and door hinges. Now, the StrikeMaster II Pro comes with the Door Edge Pro which reinforces the door and keeps it from spliting during kick-in attempts. The StrikeMaster II Pro has been installed on thousands of homes without a single failure. It does not require additional locking devices. It is powder coated white to match most homeowners’ trim color or can be painted to match any decor. The average homeowner can install it in less than 30 minutes. No cutting or removal of the door casing is necessary. The StrikeMaster II Pro will fit any outside door frame including doors with side-lights and double entry doors. Also repairs and strengthens already broken door frames.

Rated 4.4 out of 5 by 100 reviewers.
Rated 1.0 out of 5.0 by FAILED!! I installed this product after a break-in. on the 15th of July. My house was again broken into on the 24th of July. They probably had to kick the door a couple more times but it did not keep them out. it is now shaped like an 's' from Kiss' logo. Did not work. July 30, 2014
Rated 5.0 out of 5.0 by Easy to install; no issues whatsoever Well-packaged and instructions are straightforward enough to be installed in minutes. Though I have an outward swinging door I needed to reinforce the damaged strike plates as well as to add on to the benefit of having an outward swing door. Product seems solid and I can't foresee any apparent issues with it installed. May 19, 2015
Rated 4.0 out of 5.0 by Tight, but works! Looks to be great quality and a very simple install. However, after installing, my door clearance is now real tight. Have to give the door an extra push or pull to close the door now. Tried adjusting the front door and followed instructions to pound the spots where it may be a bit tight and both didn't help. The house was built around 1980 so maybe the standards then is different from now for door specifications? Who knows, but still happy with the purchase. The front door feels solid now, it'll take a lot of kicking, pounding, and screaming to get through the front door I'm sure. October 2, 2015
Rated 5.0 out of 5.0 by Every home should have these. I was surprised how simple it was to install. I have them on all my entry doors. Anyone can install this. Knowing my family is safe is a blessing. October 8, 2015
Rated 3.0 out of 5.0 by Fine once it is in but a huge pain to install This took about 4 to 6 hours to install and project planning time to decide the best approach. This item did not fit my standard door frame. I had to chisel out wood. I also had to use a multi-tool to drill out wood because the metal was too wide. Otherwise about a quarter of an inch of metal would hang past the closed door. I also had to drill a new hole for the deadbolt. July 28, 2015
Rated 3.0 out of 5.0 by LOOKS SOLID TO ME The Instructions on this Kit are not really totally understandable, There are No diagrams but there is semi detailed information. There are a few YouTube videos that are helpful Easy to install for those who are experienced at assembly and figuring stuff out, however if you are not the kind that has power tools I recommend you hire someone to install this kit. Its Really Solid. It fit with no problems and the Door still closes and opens as smooth as before. On install I need to make No adjustments. Plenty of Screws for the Locking side of the frame , however not enough to reinforce the hinge side, Apparently I got mixed up and bought the kit that did not have the hinge side reinforcement. I will have to either add another purchase to reinforce the hinge side or drive in Longer screws on the hinged side. September 15, 2015
Rated 4.0 out of 5.0 by Installation was easy...not the best looking kit. Installation was not hard at all however this is not the best looking kit. I installed this on the door going to the garage. I will probably end up buying another kit for the other door in the garage that goes to the outside because the kit was easy to install and this appears to be one of the cheapest kits for what you get. My only complaint is that the door does not shut as tight as it should, even after adjusting the tab for the door knob latch. I would not recommend putting this kit on your front door or any other door where you would want a neat appearance. It wouldn't be so bad if they made a particular kit depending on which way the door opened so you wouldn't have a cutout for a dead bolt latch to stare at. October 2, 2012
Rated 5.0 out of 5.0 by This is one of the best door security devices that I have come across. I am a toolmaker by trade and was doing online research for something that would increase my home security after having my home burglarize. The culprit kicked in my door. When I looked at the Strikemaster II Pro online I knew from my years of metal fabrication experience that this product was worth trying out. I purchased one and installed on my front door. After which, being 6'2" and 275 lbs. I personally tryed to kick my own door in to test it out before someone else did. The end result was that I ended up with a sore foot and a solid standing door. I will be purchasing 2 more to give my home the complete security that I need living out in the country. May 18, 2012
