Featuring six 3-inch screws for enhanced kick-in resistance and durable stamped alloy steel construction, it offers a secure, stylish, and easy-to-install upgrade for modern door hardware. ## Description Replace your standard, separate latch and deadbolt strike plates with one designed for maximum security. Our Defender Security Max Security Combo Strike is a one-piece combo plate that comes with six 3 inch long screws for maximum security. These longer screws allow for a strong hold, which helps prevent kick-ins. Made of stamped steel with a satin nickel finish, this door strike is strong and durable, sure to last the test of time. Installation is quick and easy, and the door strike fastens into jamb and door frame with screws. Some mortising and pilot hole drilling may be required for a flush install. This door strike features slightly taller latch and bolt openings to accommodate door hardware spaced from 5-1/2 in. to 6 in. hole centers. *Installation note: It is best to pilot drill a hole for the 3 inch long screws and use a hand operated screw driver to install the 3 inch long screws. Review: It is pretty soft metal. Prime Line and Defender are the same company. Defender brand is how this product is packaged and those are the cheap 4" and 6" brass strike plates at HD/Wally etc. Now this is a decent grade product and better than the HD/Wally junk but not even close to Don Jo etc which is real 12ga steel. I don't know what this metal is but I can bend it in the middle with significant pressure but that is not truly relative to its holding power. A thief would have to bust out the screws and 2x4 as well as the plate so it is pretty secure. This model does have a very nice nickel finish on it for the price. If you change out the screws for 3 inch stainless screws for another dollar it will hold really good. Actually you only need the 6 screws that will go into the frame. It doesn't matter the quality of the 1.5" screws much because they are only going into the 3/4" jamb. I managed to get 8 screws to bite into the frame but I removed the door outer molding so I could see where the screws were going. It was easy to chisel out the print for plate and I was pleased with the install. This product is also much easier to install than a larger or longer quality strike plate. The 1/2 inch tabs are a nice touch to add some stability too. All in all I am pleased with the purchase after installing it and it looks nice. It is way more hassle to install an 18" to 48" professional strike plate at $25 to $65+. This is kind of a nice happy medium for quality, installation and price. I was going to take a star away for being soft metal but it is priced good for what you get and I don't see it really having much impact on the situation.

It feels solid. **Q: recommended screws? I'd like to use some quality screws but have no idea what to look for, brand, size, etc** A: Comes with some very well impressive screws so no need to worry. You are in good hands with this baby. I tried as best I could to kick it in and was rewarded with boot marks and a trip to HD to get a solid wood door. Any unwelcomed intruder would need a some serious tools to get in. Make sure your locks are unpickable too.

Not unless you trim the door stop ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by R***R on 27 October 2018* It is pretty soft metal. Prime Line and Defender are the same company.
