## Overview

Crafted from stamped alloy steel with a satin nickel finish, it includes six 3-inch screws for maximum frame reinforcement, preventing kick-ins. Easy to install with surface mount design, it offers a durable, sleek upgrade to standard door strikes, trusted by thousands for enhanced home security.

## 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 inch to 6 inch 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: Security Must Have - Bought this to complete a custom door project. desertcart had best price as compared to other Hardware Stores. Screws were of good quality (be sure to pre-drill holes). Is an easy way to add extra security and reinforcement to door frames without detracting from overall appearance.

## Questions & Answers

**Q: What is the measurement from center to center of the two strike holes?**
A: 5 3/8" however, the strike holes are oversized (1 3/4") so there is quite a bit of leeway

**Q: How thick is the plate?**
A: Upon measuring, it appears to be 1/8 of an inch thick.  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. Check this outFlip Guard Satin Nickel https://www.amazon.com/dp/B00HZD8S8G/ref=cm_sw_r_em_apa_a1KOzbA6T37Y1

**Q: Will this work on a interior door frame which is not 1 3/4"?**
A: No too wide..will work on 1 3/4 but not on 1 3/8. Not unless you trim the door stop
