## 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
