1. Mark the drilling placements

In case the kit you have includes a template, you might have the option to choose between left and right-hand doors. Ensure that the template you’re using is suitable for the door, then cut it out and attach it as per the instructions. If no template is provided, follow the manufacturer’s guidelines to mark the locations of the holes. It’s critical to measure the distance from the hinge side of the door. Use a pencil to mark the distance between the holes, and then use a speed square to draw vertical lines at both pencil marks. Lastly, measure the height of each hole on the vertical pencil lines with a tape measure.

2. Drill the holes

Drill the holes

Begin by utilizing a power drill to produce pilot holes in the areas you marked. Once this is done, you can switch to the appropriate bit, which is usually 3/16, but it’s best to confirm this by checking the instructions. It is essential to not go too deep when using a drill on a door; a hole of ¾ inch is usually enough.
