How to install a door handle on a thick door?
Nov 13, 2025| Hey there! As a door handles supplier, I've seen all sorts of doors and the process of installing door handles on them. Today, I'm gonna walk you through how to install a door handle on a thick door. It might seem a bit tricky at first, but with the right steps and tools, you'll have that handle up and running in no time.
Tools You'll Need
First things first, let's talk about the tools you'll need for this job. You'll need a drill, a screwdriver (both flat - head and Phillips - head are good to have), a tape measure, a pencil, and of course, the door handle you've chosen. Make sure the drill bits you have are suitable for the material of your door. For wood doors, standard wood drill bits work well, while for metal or fiberglass doors, you'll need specialized bits.
Choosing the Right Door Handle
Before you start the installation, it's crucial to pick the right door handle for your thick door. We offer a wide range of door handles, and you can check out our Door Handles For Barn Doors if you have a barn - style thick door. These handles are not only sturdy but also add a touch of style to your door.
Measuring and Marking
The next step is to measure and mark the spots where you'll be installing the door handle. Use your tape measure to find the center of the door. For most interior doors, the handle is usually placed about 36 inches from the bottom of the door. But for thick doors, you might want to double - check this height based on your personal preference and the door's usage.
Once you've found the right height, use your pencil to mark the center point on the edge of the door. Then, measure the width of the door handle and mark the spots where the screws will go. Make sure these marks are straight and evenly spaced.
Drilling the Holes
Now it's time to drill the holes. Start with a small pilot hole at each marked spot. This helps to guide the larger drill bit and prevents the wood from splitting. After you've drilled the pilot holes, switch to the appropriate size drill bit for the screws that come with your door handle.
When drilling through a thick door, you might need to be extra careful. Go slowly and apply steady pressure. If you're using a power drill, make sure it's on a low speed setting at first to avoid any mishaps.
Installing the Door Handle
Once the holes are drilled, it's time to install the door handle. Take the two parts of the handle - the inside and outside pieces. Insert the screws through the holes in the outside piece and into the holes you drilled in the door. Then, from the inside of the door, align the other part of the handle with the screws and start tightening them using your screwdriver.
Make sure the handle is firmly attached and doesn't wobble. If it does, you might need to tighten the screws a bit more.
Testing the Handle
After the handle is installed, test it out. Open and close the door a few times to make sure the handle works smoothly. Check if the latch engages properly. If there are any issues, like the handle being too stiff or the latch not catching, you might need to make some adjustments.
