Door Hardware & Locks for Every Door

Door hardware affects how a door operates, closes, looks, and controls access. This category brings together products for new installations, repairs, replacements, and upgrades, from basic knobs and levers to more specialized locking and mounting hardware.

Use the specifications to compare compatibility before choosing. Door thickness, backset, bore size, handing, mounting method, finish, and intended location can all affect whether a product is a practical match.

How to choose door hardware and locks

Start by identifying the door and the job. An interior bedroom door may need privacy hardware, while an exterior entry door generally calls for hardware designed for more frequent use and controlled access. A closet, passageway, office, gate, or utility space may require a different function altogether.

Consider these points before comparing products:

• Door location: Decide whether the hardware is for an interior, exterior, entry, bathroom, bedroom, closet, cabinet, or utility door.
• Existing cutouts: Replacement hardware must often align with the door’s current bore, backset, and strike placement.
• Door dimensions: Check the compatible door thickness and any required clearance around the frame.
• Operation: Choose between a knob, lever, pull, handle set, deadbolt, latch, or another mechanism based on how the door will be used.
• Installation: Look for products that match the available mounting holes and include the components needed for installation.

If the project involves a lock replacement, compare the complete dimensions rather than relying only on appearance. Small differences in the latch, strike, or cylinder can affect fit and operation.

Common types to compare

Door hardware can be grouped by function. Passage hardware is suited to doors that need to open and close without locking, while privacy hardware is typically intended for rooms where temporary interior locking is useful. Entry hardware combines a handle or knob with a locking function for doors that require controlled access.

Deadbolts are another common choice for entry doors. Compare single-cylinder and other available configurations according to the door layout and how the lock will be operated. Lever handles may be easier to operate than knobs in some settings, while pull handles and push plates may suit commercial or high-traffic doors.

For security products used separately from standard door sets, browse Padlocks & Hasps. Projects involving cabinets, furniture, or shelving may be better served by Cabinet Hardware, Furniture Hardware, or Shelf Brackets & Supports.

Key features and specifications

The most useful product details depend on the hardware type, but several specifications are worth checking across the category:

• Material and finish: Materials affect durability and appearance; finishes should coordinate with hinges, pulls, faucets, and other nearby fixtures.
• Lock type and cylinder: Compare the locking mechanism, keying arrangement, and whether the product is intended for keyed or non-keyed operation.
• Latch and backset: These dimensions are especially important when replacing existing hardware.
• Handing: Some levers and handles are reversible, while others are designed for a specific left- or right-hand door.
• Included components: Check whether the package includes the latch, strike plate, keys, mounting screws, and other installation parts.
• Intended use: Look for specifications that indicate residential, commercial, interior, exterior, or high-use applications when relevant.

For doors exposed to moisture, compare the material and finish carefully. Bathroom projects may also benefit from browsing Bathroom Hardware for coordinating accessories and installation needs.

Brands represented in the catalog

The catalog includes door hardware and lock products from Prime-Line, Prime-Line Products, Kwikset, Amazon Basics, SCHLAGE, Probrico, M-D Building Products, SMARTSTANDARD, National Hardware, Hager, skysen, and Yale. Brand selection varies by product type, so compare the specifications of individual listings rather than choosing by brand name alone.

For broader home projects, the Hardware category can help connect door-related purchases with other general hardware needs. Tarps & Tie-Downs is another related catalog area for securing and covering items, though it serves a different purpose from door locks and fittings.

Installation and compatibility tips

Before removing existing hardware, photograph the installation and measure the important openings. Confirm the door thickness, backset, bore diameter, edge bore, hinge-side clearance, and strike location where applicable. Make sure the new hardware will not interfere with trim, weatherstripping, screens, or nearby walls.

For exterior applications, pay attention to weather exposure and the condition of the door and frame. A new lock may not correct problems caused by a misaligned frame, loose hinges, or a door that does not close cleanly. Follow the product’s installation instructions and verify that the latch and lock engage smoothly before regular use.

Frequently asked questions

How do I know whether replacement door hardware will fit?

Check the existing door’s thickness, backset, bore size, handing, and mounting-hole pattern against the product specifications. Matching the finish alone is not enough.

What is the difference between passage and privacy hardware?

Passage hardware is generally used where locking is not needed. Privacy hardware is intended for interior spaces where temporary locking is useful, such as bedrooms or bathrooms.

Should I choose a knob or a lever?

Both can work for many doors. A lever may be easier to operate for some users, while a knob can suit traditional designs or locations with limited surrounding space.

What should I compare for an exterior door?

Review the lock function, cylinder type, compatible door dimensions, material, finish, included parts, and suitability for exterior exposure. Also check that the frame and strike are properly aligned.

Can door hardware be used on cabinets or furniture?

Some products are designed specifically for cabinets or furniture, but standard door hardware is not automatically compatible. Compare the intended application and dimensions before purchasing.
