Common questions
Which grade is best?
Grade 1 is the strongest and best for entry doors. Grade 2 is fine for most homes. Grade 3 is light duty.
Can I put a smart lock?
Yes. Smart deadbolts fit the same hole in most doors. Check that it works with your phone or hub and has a key backup.
Is a double cylinder needed?
Usually not. They need a key inside too, which can slow you in a fire. Fire codes limit them, so a single cylinder is the norm.
