During most home burglaries, criminals enter the home by kicking in the door. They can do this because, regardless of the quality of the deadbolt or the weight of the door, most homes are protected only by a flimsy piece of metal (the strike plate into which the deadbolt locks in place) and a ¾” inch piece of wood that secures the strike plate.


One of the most cost-effective home improvement projects, replacing your common strike plate with the Sure-Strike strike plate system adds strength and security to your doorframe and helps prevent kick-in burglaries.


Almost four years of designing, engineering and testing, along with the feedback from hundreds of locksmiths and hardware experts, have gone into Sure-Strike. The Sure-Strike housing embeds into both the king and jack studs of your doorframe and is secured with #8 3 1/2” screws. This, along with the combined thickness of the cover plate and flange of the Sure-Strike, make it the highest-quality strike plate in the home improvement market.


In addition to making your home more secure, however, Sure-Strike’s patented multi-pin technology is what really makes it unique. The rows of pins surrounding the deadbolt “hole” are retractable on impact. As a result, the retractable pins allow the Sure-Strike strike area to accommodate your off-center deadbolts. In essence, the Sure-Strike strike area moves to wherever your deadbolt requires - whether the deadbolt is striking to the right of the hole, to the left, above the hole, or below. That’s why it’s the strike plate that makes deadbolts dead-on.

The patented adjustable pin function and larger opening of the Sure-Strike allows your deadbolt to enter the Sure-Strike when doorframe shifting or door swelling occurs, correcting for up-and-down or side-to-side misalignment.

This unique design doesn’t just make your doors easier to lock. It makes them more secure as well. Unless your deadbolt shaft can travel to its full extension—which can be impossible if the door has shifted—your door may not even be fully locked. When that’s the case, a thief could easily insert a screwdriver or other tool and move your deadbolt shaft back and enter your home.


Sure-Strike puts an end to perpetually moving your strike plate to match up to your deadbolt and trips to the hardware store for solutions that don't permanently fix the problem. Not only can the constant moving of your strike plate make for an ugly door, but the continual degradation of your doorjamb makes your door even less secure.


Sure-Strike is made of high performance composites with the ability to survive extreme climate changes. The inner workings of the Sure-Strike are made of stainless steel, making it highly resistant to corrosion and rust. The cover plate is made of cold-rolled steel and is much thicker than the common strike plate. The 3-1/2” screws are made of hardened steel.


The Sure-Strike is hidden away into the doorjamb and is hardly noticeable. It also comes in various finishes to match your existing door hardware.  In addition, the Sure-Strike cover plate often covers all prior damage from moving the common strike-plate back and forth.


After installing Sure-Strike, you will notice that your doors close more tightly against the weather strip of the doorjamb. Sure-Strike pays for itself by keeping your heating and cooling bills down.
