Before You Buy Door Hardware

  • Identify the door type: swinging, pocket, bypass, bifold or wall-mounted sliding.
  • Measure the door: record its width, height and thickness.
  • Check the door weight: heavy solid-core doors require properly rated hardware.
  • Measure the opening: sliding and folding systems must match the finished opening.
  • Choose the function: passage, privacy, keyed entry or inactive hardware.
  • Check existing preparation: measure bore holes, backset and hinge locations.
  • Determine handing: some locks, levers and specialty parts are handed.
  • Select a finish: coordinate nearby hinges, pulls, locks and accessories.

Main Types of Door Hardware

Hinges

Hinges attach a swinging door to its frame. Common residential doors use butt hinges, while heavier doors may need larger hinges, additional hinges or ball-bearing hinges.

Match the hinge size, corner shape, screw pattern, door thickness and finish to the door and frame.

Knobs and Levers

Knobs and levers operate the latch on a standard swinging door. Levers are generally easier to grip, while knobs provide a traditional appearance.

Verify the backset, door thickness, bore-hole size and required function before ordering.

Passage Hardware

Passage knobs and levers latch the door but do not lock. They are commonly used for hallways, closets, laundry rooms and other areas where privacy is not required.

Privacy Hardware

Privacy hardware includes a simple locking feature for bedrooms and bathrooms. It usually provides an emergency-release feature on the hallway side.

Keyed Entry Hardware

Keyed knobs, levers and deadbolts are intended for doors that require controlled access. For exterior doors, choose hardware specifically designed for exterior exposure and security.

Dummy Hardware

Dummy knobs and levers do not turn or latch. They are used as decorative pulls on inactive double doors, closets and other doors secured by separate hardware.

Pocket Door Hardware

Pocket doors slide into a wall cavity. A complete system may include a frame, overhead track, roller hangers, door plates, guides, stops, pulls, locks and optional soft-close components.

Pocket Door Pulls and Locks

Pocket doors normally use recessed flush pulls so the door can enter the wall. An edge pull helps retrieve a fully opened door. Privacy locks are available for bedrooms and bathrooms.

Bifold Door Hardware

Bifold systems use hinged door panels that fold as they move along a top track. Hardware typically includes the track, pivots, roller hangers, alignment components and panel hinges.

Bypass Door Hardware

Bypass doors move along parallel tracks and slide past one another. They are commonly used for closets and wide openings where a swinging door would take up too much room.

Barn and Wall-Mount Hardware

Wall-mounted sliding doors travel along a track installed above the opening. Confirm that the wall can support the track and that there is enough clear wall space for the door to open completely.

Door Stops

Door stops protect walls, trim and nearby fixtures. Common styles include baseboard stops, hinge-pin stops, floor stops and magnetic holders.

Closers and Soft-Close Devices

Door closers return swinging doors to a closed position. Soft-close mechanisms slow sliding doors near the end of travel to reduce slamming and provide more controlled operation.

Flush Bolts

Flush bolts secure the inactive panel of a pair of swinging doors. They are installed into the edge or face of the door and engage the header, floor or threshold.

Thresholds and Weathersealing

Thresholds create a transition at the bottom of an opening. Exterior thresholds, sweeps and weatherstripping also help limit drafts, water and debris.

Measurements to Check

Door Thickness

Hardware must accommodate the thickness of the door. This is especially important for locksets, pocket door locks, hangers, pivots and mounting screws.

Backset

Backset is the distance from the edge of a swinging door to the center of the knob or lever bore. Purchase a latch that matches the existing backset.

Bore-Hole Diameter

Replacement locksets must fit the holes already drilled in the door. Measure both the large face bore and the smaller edge bore.

Door and Opening Width

Sliding and folding hardware is normally selected according to the door width, number of panels and finished opening width.

Track Length

Track must provide enough travel for the door arrangement. Do not assume that track length is always the same as the opening width.

Door Weight

Use hardware rated above the actual weight of the door. Solid wood, oversized, mirrored and glass doors may require heavy-duty track, hangers or hinges.

Understanding Door Handing

Some hardware is reversible, while other products are manufactured for a particular door handing. Handing is normally determined by the side where the hinges are located and the direction in which the door swings.

Before buying a handed lock, lever, closer or specialty component, stand on the side specified by the manufacturer and follow that manufacturer's handing instructions. Handing terminology can vary between product categories.

Helpful tip: Take photographs of the door from both sides, including the hinges, latch edge and existing hardware. Keep the photos with your measurements while shopping.

Hardware Material and Finish

Finish

Common finishes include satin nickel, polished chrome, brass, bronze, black and stainless steel. Slight color differences can occur between manufacturers.

Location

Interior hardware does not always have the corrosion resistance needed for exterior, coastal or high-moisture locations. Select hardware rated for the intended environment.

Durability

Frequently used doors benefit from stronger components, ball-bearing rollers, quality hinges and replaceable wear parts.

Standard-Duty or Heavy-Duty?

Standard residential hardware may be suitable for lightweight doors with occasional use. Consider heavy-duty hardware when the door is unusually large, heavy or frequently operated.

  • Solid-core or solid-wood doors
  • Oversized or extra-tall doors
  • Wide closet door systems
  • Mirrored or glass-panel doors
  • High-traffic residential openings
  • Commercial or multi-unit applications
  • Doors using soft-close accessories
  • Projects where long-term serviceability is important

How to Select the Right Hardware

  1. Identify how the door moves.
    Determine whether it swings, slides into a wall, folds or moves across the face of a wall.
  2. Measure the door and opening.
    Record the width, height, thickness, opening size and available clearance.
  3. Determine the door weight.
    Confirm that hinges, rollers, hangers, pivots and tracks are rated for the door.
  4. Select the required function.
    Decide whether the door needs passage, privacy, keyed locking or non-operating decorative hardware.
  5. Check compatibility.
    Make sure all tracks, rollers, locks and accessories are designed to work together.
  6. Review installation requirements.
    Confirm framing, blocking, clearances and door preparation before ordering.

Common Buying Mistakes

Buying by Appearance Alone

A product may look correct but still have the wrong backset, thickness range, handing or weight capacity.

Ignoring Door Weight

Underrated rollers, tracks or hinges can cause difficult operation, sagging and premature wear.

Mixing Incompatible Parts

Rollers, tracks, brackets and soft-close devices are not always interchangeable between systems or manufacturers.

Ordering Before Measuring

Small differences in door thickness, track length or opening width can determine whether a system fits correctly.

Forgetting the Pull or Lock

Track hardware may not include the visible pull, handle or privacy lock required to operate the finished door.

Overlooking Installation Access

Pocket doors and concealed tracks should be planned so that adjustments and future maintenance remain possible.

Frequently Asked Questions

Can I reuse my existing door hardware?

Often, but inspect each part for wear and confirm that it is compatible with the new door's thickness, weight, preparation and intended use.

Do door knobs and levers fit every door?

No. Check the door thickness, bore-hole diameter, backset, handing and lock function before buying.

What hardware does a pocket door need?

A typical pocket door needs a frame or structural pocket, overhead track, roller hangers, mounting plates, door guides, stops and a recessed pull. Privacy applications may also require a pocket door lock.

Are bifold and bypass door systems the same?

No. Bifold panels are hinged together and fold as they travel. Bypass doors remain flat and slide past one another on parallel tracks.

When should I use heavy-duty hardware?

Use heavy-duty hardware for heavy, oversized or frequently operated doors, and whenever the door weight approaches the limits of standard hardware.

Can hardware from different systems be combined?

Do not assume that it can. Tracks, rollers, hangers, pivots and soft-close devices may have system-specific dimensions. Confirm compatibility before combining components.
