Thick doors, often found in commercial settings, historical homes, or high-security applications, present unique challenges when choosing door hardware. Standard door hardware simply won't cut it; you need solutions designed to accommodate the increased thickness and often, the heavier weight. This guide will explore the intricacies of selecting the right door hardware for your thick door, addressing common concerns and offering expert advice.
What Constitutes a "Thick Door"?
Before diving into specific hardware, let's define what we mean by a "thick door." Generally, a door exceeding 1 ¾ inches in thickness is considered thick. Doors exceeding 2 inches are significantly thick and require specialized hardware. The exact thickness will influence the hardware choices, so always measure your door precisely before purchasing anything.
Types of Door Hardware for Thick Doors
Several types of door hardware are specifically designed for thick doors, catering to different needs and aesthetics:
1. Extended-Reach Door Hardware:
This is the most common solution. Extended-reach hardware features longer screws, faceplates, and sometimes even longer spindles, allowing for secure installation on thicker doors. You'll find extended-reach options for almost all types of door hardware, including:
- Doorknobs: Look for doorknobs explicitly labeled "for thick doors" or those with adjustable backsets.
- Door Levers: Similar to doorknobs, extended-reach levers are readily available. Consider the style and finish to match your door and interior design.
- Deadbolts: Extended-reach deadbolts are crucial for security, ensuring the bolt extends far enough to engage the strike plate securely.
- Handlesets: Handlesets that come as a single unit often have extended reach components built in, simplifying installation.
2. Mortise Locks:
Mortise locks are a more robust and sophisticated option, ideal for high-security applications and thicker doors. These locks are installed directly into the door itself rather than surface-mounted, offering superior strength and protection against forced entry.
3. Custom-Made Hardware:
For exceptionally thick doors or unique architectural styles, custom-made hardware might be the only viable option. A skilled locksmith or metalworker can create bespoke hardware to meet your exact specifications. This route is usually more expensive but guarantees a perfect fit and a unique aesthetic.
What to Consider When Choosing Hardware for Thick Doors
Backset:
The backset is the distance between the edge of the door and the center of the doorknob or lock. Standard backsets are 2 ¾ inches and 2 3/8 inches, but for thick doors, you may need a longer backset, sometimes up to 4 inches.
Material:
Consider the material of the hardware. Solid brass or stainless steel is durable and resistant to damage, especially suitable for high-traffic areas.
Finish:
Choose a finish that complements your door and interior design. Options range from polished chrome to oil-rubbed bronze and matte black.
Security:
For added security, choose hardware with a high-quality deadbolt, preferably one with a longer throw bolt.
How to Install Door Hardware on Thick Doors
While some extended-reach hardware installation is relatively straightforward, the process can be more challenging than with standard-thickness doors. If you are uncomfortable with DIY installation, always consult a professional locksmith or handyman. Incorrect installation can compromise security and door functionality.
Frequently Asked Questions
What is the maximum thickness a standard doorknob can handle?
Most standard doorknobs are designed for doors up to 1 ¾ inches thick. Beyond this, extended-reach hardware is necessary.

No, a standard deadbolt will not provide sufficient security or proper latching on a thick door. You'll need an extended-reach deadbolt.
Are there specific brands that make hardware for thick doors?
Many reputable brands offer extended-reach door hardware, but it's crucial to check the specifications to confirm compatibility with your door thickness. Some examples include Schlage, Kwikset, and Baldwin, but always consult individual product details.
