How to choose door locks for French doors

French doors offer a great way to create an open, bright space in your home while still maintaining the option for privacy. They often feature glass from top to bottom and are an easy way to add a little charm and character. But how do you purchase the right door hardware for French doors? Here’s what you need to know before you head out to the hardware store.

Pre-shopping checklist

Before you choose your hardware, there are a few things you will need to note about your door. First, notice how it has been prepped. Are the bore holes already drilled into the door or is the panel where the hardware will be placed solid? This will help you choose the function of your hardware. For doors that do have bore holes, check out this door prep checklist to ensure your door has been prepped to standard measurements.

If you are planning to purchase a lever with a curve, you’ll want to note the handing of your doors. Since you will have both a left and right-handed door, be sure to choose both a left-handed lever and a right-handed lever.

Interior french doors – no bore holes

Interior French doors are often used to separate an office or den from the rest of the home when privacy or noise control are needed, while still giving the space an open feeling. You can also find them as a formal entrance to a master suite or even in large closets. They are sometimes referred to as double doors and can be solid or feature head-to-toe glass.

For double doors that do not have bore holes, you can choose to use non-turning or dummy function hardware. These are often used as decorative door pulls when the ability to latch or lock the door is not needed. For shallow closets, you can get by with installing door hardware only on the exterior side of the door. For larger rooms you can actually walk into, make sure to purchase enough non-turning door knobs or levers for the interior side.

Interior french doors – with bore holes

For rooms you would like to be able to lock or just prefer to have a working knob or lever that latches, you will want to purchase French doors that are already drilled with a cross bore hole on one side and a latch bore on the other. Let’s say the cross bore hole is on the right handed door. If you want to have the option to lock the door, choose a Bed & Bath / Privacy function for your knob or lever. If locking is not necessary but you would like the door to latch, choose a Hall & Closet / Passage function. You can then choose a non-locking/dummy lock for the left-handed door.

Exterior Patio French Doors - with bore holes

Exterior French doors are most commonly used to access outdoor living spaces, like a sunroom or patio. They offer a stylish way to make the transition from one space to another seamless. You can also choose double doors for the front of your home as an elegant entryway.

You can choose an exterior set of doors that is prepped similarly to the interior doors with bore holes on one side, but if you want to add a little extra security, make sure you have a second bore hole to house a deadbolt. A single cylinder mechanical deadbolt will do. Some homeowners prefer to install a double cylinder deadbolt for even more security with glass doors. Beneath the deadbolt, you can choose a keyed knob or lever.

For a more formal look, choose a handleset. For the inactive side of the door, you can choose to install nothing at all but if you want to complete the look, install the non-turning/dummy function of the same lock combo you chose for the active side.

Exterior Double Doors - with Electronic Locks

What about electronic and smart locks? All of our electronic and smart locks are compatible with any standard door so that means you can install them on your French or double entry doors just the same as you would a mechanical deadbolt. The double entry door above features a Schlage Sense Smart Deadbolt paired with the Camelot style front entry handle. If you only have two bore holes, you can add a passage knob or lever below your smart or electronic lock.
