Door hardware affects safety, accessibility, security, and the look of a space. Levers, closers, and exit devices need to work together, not just match the interior. This door hardware selection guide follows a practical order: decide how each opening should behave, then choose its material and finish. Before ordering, verify applicable requirements with the authority having jurisdiction (AHJ), the body responsible for local code approval.

1. Start with how the door should behave

Before looking at shapes or finishes, write a short brief for each opening: who uses it, from which side, when it must lock or stay unlocked, and whether it needs card or code access. Those answers help determine the lock and exit-device functions.

• Entrance: free exit from inside, with key or credential access from outside.
• Office: an inside locking control, outside key override, and free exit.
• Storeroom: the outside lever stays locked, with entry by key or an approved access-control arrangement.
• Classroom: a key locks or unlocks the outside lever; the inside lever always allows exit.
• Egress-only: an exit device inside, with no outside entry function.

The Doors For Pros overview groups locksets, exit devices, hinges, closers, and trim in one place, making it useful for identifying the parts an opening needs. Confirm each manufacturer’s function description before specifying: a matching lever style does not mean two locksets operate the same way.

2. Safety and accessibility you can’t ignore

Under the U.S. 2010 ADA Standards for Accessible Design, accessible door hardware must work with one hand, without tight grasping, pinching, or wrist twisting. Operating force is limited to 5 lbf (about 22 N), and hardware generally mounts 34 to 48 inches (about 865 to 1,220 mm) above the floor.

Interior hinged doors generally have a 5 lbf opening-force limit, with exceptions for fire doors and separate treatment of latch retraction. Closers must take at least 5 seconds to move a door from 90 to 12 degrees. Thresholds are generally limited to 1/2 inch (about 13 mm), with profile requirements and some exceptions. Check the applicable provisions rather than using these figures as a complete specification.

For Indian projects, start with the Government of India’s Harmonised Guidelines and Standards for Universal Accessibility in India 2021 and applicable local requirements. Confirm which standards and amendments govern the project with the AHJ. U.S. benchmarks are not a substitute for local compliance.

3. Fire, egress, and listings

Panic hardware and fire exit hardware can look alike, but they are not interchangeable. Panic hardware may allow mechanical dogging, which holds the latch retracted for free passage. Fire exit hardware is intended for rated doors and cannot be mechanically dogged. The assembly must close and latch when required for fire protection.

Where smoke control is required, check the assembly’s smoke-leakage requirements, including any required “S” mark and seals under the applicable listing system. A fire rating alone does not establish smoke-leakage performance.

Specify the door, frame, hardware, and seals as a compatible assembly under the applicable listings and installation instructions. Unapproved substitutions or field modifications can compromise the rating, so obtain approval before making changes. U.S. listing references do not automatically establish compliance in India.

4. Hardware grades and what they signal

ANSI/BHMA standards grade hardware categories through defined performance tests. For many common categories, Grade 1 represents the highest performance grade. Compare grades within the same category, and remember that a test grade does not guarantee service life. Use the commercial door hardware overview to organise a shortlist, then check the exact model and function in the manufacturer’s documentation and BHMA Certified Products Directory.

A finish may carry both a BHMA code and a traditional U.S. code. Similar-looking finishes can use different base materials:

5. Materials and finishes for Indian climates

Finish choice affects both appearance and maintenance. Match the material to the exposure before choosing its colour:

• 304 stainless steel suits many interior and inland applications.
• 316 stainless steel resists chloride pitting better than 304 and is often preferable near coasts. Pool and industrial settings still need an exposure-specific recommendation from the manufacturer.
• PVD coatings provide a thin, hard surface in tones such as black, bronze, or brass. Performance depends on the base metal and coating quality. Check wear and corrosion test data; on-site refinishing is generally impractical.
• Powder coating offers colour flexibility but can chip at exposed edges. It may suit closer covers and lower-contact trim better than heavily used pull ends.

For a consistent look, choose one finish family and one lever or pull profile for public areas, while varying lock functions as needed. Follow the manufacturer’s cleaning instructions. Remove salt and cleaner residue with fresh water and a soft cloth, and avoid chloride-based cleaners on stainless steel.

6. Closers, hinges, and the feel of the door

How a door feels depends largely on its closer, hinges, and alignment. Closer size sets spring power: too much makes opening difficult; too little may prevent reliable latching against air pressure. A regular arm is generally efficient, while a parallel arm is less prominent on the push side. Follow the manufacturer’s sizing guidance for the chosen arrangement. Heavy or wide doors may benefit from pivots or continuous hinges.

A sagging door can make opening-force and closing-time requirements difficult to meet. Check frame alignment, hinge condition, seals, and latch engagement before increasing closer power. Scheduled adjustment can resolve problems that a product upgrade alone will not fix.

7. Access control choices without code traps

Check what each electrified device does when power fails. Fail-safe devices unlock; fail-secure devices remain locked on the secure side. A fail-secure lock can still allow mechanical exit through its inside lever. Choose the power-loss state for each opening, then verify egress separately. Entry security must not prevent occupants from exiting as required by local code.

Fire-rated doors also need positive latching: the latch must engage and hold the closed door. A magnetic lock alone does not provide this function. Confirm that locks, strikes, and other components are approved for the rated assembly. Bring the architect, security integrator, and hardware supplier into one review before ordering frames, so wiring routes and hardware preparations are planned rather than improvised on site.

8. Style that works hard

Once function is settled, choose shapes that suit the interior. Slim straight levers and flat-bar pulls often suit modern offices; fuller profiles and warm finishes can complement heritage and hospitality spaces. Keep levers operable without tight grasping, and allow enough clearance behind pulls for fingers. Repeating a profile creates visual consistency without requiring every door to use the same lock function.

Some jurisdictions and healthcare or education clients require return-to-door levers, whose ends curve toward the door face to reduce snagging. Confirm this early because it narrows the available profiles.

9. Quick spec checklist

• Door type, dimensions, thickness, and hardware preparations
• Handing and swing direction, using the manufacturer’s convention
• Lock or exit-device function code
• Fire-rating and smoke-control requirements for the complete assembly
• Accessibility requirements: mounting height, operating force, closing time, and threshold
• Required performance grade and exact-model certification
• Material and finish code, matched to exposure and cleaning conditions
• Closer size, arm type, and hinge or pivot choice
• Access-control arrangement: power-loss state, free exit, wiring, and positive latching
• Local applicability confirmed with the AHJ
