## Questions & Answers

**Q: Hinge plate template was not in package. Does it arrive separately ?**
A: Same with me, arrived end of October 2020 and it does not include a hinge template despite the photos and description - seriously!?

**Q: What size chuck is required for the drill bits? Is 3/8" sufficient? I've noticed a couple competitors require 1/2". Thanks**
A: 3/8" worked for me fine.  Both steel and wood doors (i used a different hole saw for the steel).  All assuming your 3/8" drill has enough power.  My cordless 19 volt drill was great.

**Q: Is the hole saw 2 1/8"?**
A: The big hole saw is 2 1/8. The small hole saw is 7/8, which is a little small compared to the standard 1 inch that most door lock require. Although, the deadbolt that I installed worked good with 7/8 on the door. For the door jam hole, I use a 1 inch drill not included in the kit.

**Q: Will this work on a 2 1/4 inch thick door?**
A: I do not see why not you may have to drill hole on both side pilot hole through the hole saw on both sides. the only issue I see is the hole in the side for the tongue
