Step 1: Measure Your Bore Hole
Standard Door Preparation for Deadbolts

Most doors are drilled with the same standard bore hole diameter that the majority of brands are designed to fit. This standard door preparation is a 2 1/8" diameter bore hole with a 1" cross bore. To measure your bore hole, just hold up a measuring tape or ruler across the bore hole as shown in the graphic above. The 2 1/8" is 2 little marks past the #2 on your measure tape (also shown in the image). There are standard backsets too, but we'll get to those on the next page. Choose from the options above and we'll direct you further to find what you need.
