What Is Door Hardware?
Door hardware refers to every mechanical and decorative component installed on a door that allows it to open, close, latch, lock, or function properly. This includes knobs, levers, deadbolts, hinges, door pulls, locksets, smart locks, and accessories like door stops and kick plates.
Door hardware is grouped into two main categories: functional hardware, which controls how a door operates (locks, latches, hinges), and decorative hardware, which contributes to the style and finish of a space (knobs, levers, pulls, escutcheons).
The Main Types of Door Hardware
Understanding the basic categories of door hardware is the first step in choosing the right product for your door.
1. Keyed Entry Locksets
Keyed entry locks are used on exterior doors and any interior door that requires security. They lock and unlock with a key from the outside and typically include a turn button or thumbturn on the inside. Front doors, side entry doors, and garage-to-home doors usually use keyed entry hardware.
2. Privacy Locksets
Privacy locks are designed for bedrooms and bathrooms. They lock from the inside, usually with a push button or thumbturn, and include an emergency unlock feature on the outside in case someone gets locked in.
3. Passage Locksets
Passage sets don't lock at all. They're used for closets, hallways, pantries, and any door that simply needs to latch closed without privacy or security requirements.
4. Dummy Locksets
Dummy hardware is purely decorative. There's no latch and no moving mechanism — it's surface-mounted to one side of a door for visual symmetry. Common uses include double doors, French doors, and closet doors with roller catches.
5. Deadbolts
A deadbolt is a separate lock installed above a keyed entry handleset for added security. Single-cylinder deadbolts use a key outside and a thumbturn inside, while double-cylinder deadbolts require a key on both sides.
6. Smart Locks
Smart locks like the August Smart Lock add keyless entry, remote access, and smart home integration. Most modern smart locks replace your existing deadbolt and connect to Wi-Fi, Bluetooth, or hubs like HomeKit, Alexa, and Google Home.
7. Hinges
Hinges connect the door to the frame and allow it to swing. Standard residential doors use three hinges per door, typically in 3.5-inch or 4-inch sizes with square or radius corners.
8. Door Pulls and Knockers
Door pulls, handles, and knockers are commonly used on entry doors, barn doors, and cabinet-style applications. They're available in dozens of styles and finishes to match the rest of your hardware.
Understanding Door Hardware Terminology
Most ordering mistakes happen because of unfamiliar terminology. Here are the key terms every buyer should understand before purchasing door hardware.
Backset
The backset is the distance from the edge of the door to the center of the bore hole where the knob or lever installs. The two standard backsets in residential hardware are 2-3/8 inches and 2-3/4 inches. Most modern locksets include an adjustable latch that works with both.
Door Thickness
Standard interior and exterior doors are 1-3/4 inches thick. However, custom, solid wood, and high-end doors can be 2 inches thick or more. Thicker doors require hardware specifically rated for that thickness — otherwise, the spindle, screws, or deadbolt won't engage correctly. RightSet Hardware carries Schlage and Baldwin hardware designed for 2-inch doors.
Handing (Left-Hand vs. Right-Hand)
Handing refers to which side a door is hinged on and which direction it swings. Stand on the outside of the door (the side you push to enter the room):
- If the hinges are on your left, it's a left-hand door
- If the hinges are on your right, it's a right-hand door
Many levers and handlesets are reversible, but some — especially decorative or single-action handlesets — require correct handing at the time of order.
Bore Hole
The bore hole is the round hole drilled through the face of the door where the lockset is installed. The standard bore hole is 2-1/8 inches in diameter, with a 1-inch edge bore for the latch.
Strike Plate
The strike plate is the metal piece installed on the door frame that the latch or deadbolt engages with. A properly installed strike plate is essential for security and smooth operation.
Rosette and Escutcheon
A rosette is the round or square decorative trim plate behind a knob or lever. An escutcheon is a longer trim plate that often covers both the knob and the keyhole on an entry handleset.
Door Hardware Finishes Explained
Finish is one of the biggest decisions in door hardware. Finishes affect both the visual style of your space and how the hardware ages over time. Here are the most common finishes:
- Satin Nickel — A warm silver tone with a soft matte sheen. The most popular modern finish.
- Polished Chrome — Bright, mirror-like silver. Great for contemporary and modern spaces.
- Oil-Rubbed Bronze — A dark, hand-finished brown with copper undertones. Pairs well with rustic and traditional styles.
- Matte Black — A flat, true black finish. Common in modern farmhouse and contemporary designs.
- Polished Brass — Bright, warm gold tone. A classic finish making a major comeback.
- Unlacquered Brass — Raw brass that develops a natural patina over time.
- Flat Black vs. Matte Black — Slight variations in sheen; always confirm finish codes when matching across brands.
When mixing brands, request finish samples whenever possible. Two manufacturers' "satin nickel" finishes can vary noticeably under different lighting.
How to Choose the Right Door Hardware
Choosing the right door hardware comes down to four key questions:
1. What Function Does the Door Need?
Match the function to the room. Bedrooms and bathrooms need privacy. Exterior doors need keyed entry plus a deadbolt. Closets need passage. Double doors often pair active hardware with dummy hardware.
2. What Door Thickness Are You Working With?
Measure your door before ordering. Standard hardware fits 1-3/8 to 1-3/4 inch doors. Thicker doors require thick-door kits or hardware rated for 2-inch doors.
3. What Style Fits Your Space?
Consider the overall design of your home — modern, traditional, transitional, farmhouse, or industrial. Choose lever or knob shapes and finishes that complement your trim, lighting, and cabinetry hardware.
4. What Finish Are You Committing To?
Door hardware is one of the most visible details in your home. Pick a finish that coordinates with your faucets, lighting, and cabinet hardware — and one you'll still love five years from now.
Door Hardware Brands to Know
Several manufacturers dominate the residential door hardware market, each with its own strengths.
- Emtek — Designer hardware with extensive customization, premium finishes, and high-end residential appeal.
- Schlage — Industry-leading security, durability, and a wide range of styles. Trusted by builders for decades.
- Baldwin — Premium forged brass construction with classic and contemporary designs.
- August — Leading smart lock manufacturer offering keyless entry and full smart home integration.
- Kwikset — Reliable, budget-friendly hardware with features like SmartKey re-keying.
Choosing a trusted brand means better materials, longer warranties, and more dependable performance over time.
Smart Locks: Are They Worth It?
Smart locks have become one of the fastest-growing categories in door hardware. They allow keyless entry, remote unlocking, scheduled access for guests, and integration with smart home systems.
Benefits of smart locks include:
- No more lost keys or hidden spares
- Remote access from anywhere via your phone
- Activity logs showing who came and went
- Voice control through Alexa, Google Home, or Apple HomeKit
- Auto-lock when you leave the house
Most smart locks like the August Smart Lock install over your existing deadbolt, keeping your exterior hardware untouched while adding modern functionality.
Common Door Hardware Mistakes to Avoid
Even experienced installers make these mistakes — here's what to watch out for:
- Ordering the wrong backset — Always measure before ordering. A 2-3/8 inch lockset will not work on a door drilled for 2-3/4 inch backset without an adjustable latch.
- Ignoring door thickness — Hardware made for 1-3/4 inch doors will not function correctly on a 2-inch door.
- Mixing inconsistent finishes — Slight differences in finish between brands can be jarring. Stick to one manufacturer per room when possible.
- Skipping the deadbolt — A handleset alone is not enough security for an exterior door. Always install a deadbolt on entry doors.
- Forgetting the strike plate upgrade — A reinforced strike plate with 3-inch screws dramatically improves door security against kick-in attacks.
Door Hardware Installation Basics
Most residential door hardware can be installed with basic tools: a Phillips screwdriver, a tape measure, and occasionally a drill. Standard pre-drilled doors accept most modern hardware without modification.
For thicker doors, retrofits, or smart locks, follow manufacturer instructions carefully — and don't hesitate to contact RightSet Hardware if you have compatibility questions before installation begins.
Why Quality Door Hardware Matters
Door hardware is one of the most-touched details in your home. Cheap hardware loosens, finishes wear off, and locks fail at the worst times. Investing in quality hardware from trusted brands like Emtek, Schlage, Baldwin, and August means smoother operation, better security, and a finished look that lasts for years.
