1. Door Closers
Purpose: Automatically close the door after it's opened, ensuring secure closure and compliance with fire safety codes.
Types of Commercial Door Closers:
- Surface-mounted closers: Most common and versatile; mounted on the push or pull side of the door.
- Overhead concealed closers: Installed in the door frame for a cleaner look, common on glass or aluminum doors.
- Floor closers: Hidden in the floor; ideal for heavy doors or all-glass configurations.
- Spring hinges: Used in lightweight doors or for secondary closures.
Key Considerations:
- Adjustable closing and latching speed
- Backcheck and delayed action features
- UL-listed for fire-rated doors
- ADA compliance (low opening force)
2. Exit Devices and Panic Bars
Purpose: Provide a quick, code-compliant way to exit during emergencies.
Types:
- Rim exit devices: Surface-mounted with a latch that engages the frame.
- Vertical rod exit devices: Secure both top and bottom of the door; used on double doors.
- Mortise exit devices: Contain the locking mechanism inside the door.
Fire-Rated vs. Non-Fire-Rated:
- Fire-rated exit devices have no dogging feature and must re-latch after each use.
Best Applications: Schools, theaters, churches, offices, healthcare
facilities, and any building with 50+ occupants.
3. Locking Hardware and Key Systems
Purpose: Control and restrict access to a building or specific rooms.
Types:
- Cylindrical locks: Installed in the face of the door; easy to install and replace.
- Mortise locks: More durable; recessed into the door with integrated latch and deadbolt.
- Deadbolts: Adds additional security for storage or back-of-house areas.
- Electric strikes and magnetic locks: Used in access control systems for remote locking/unlocking.
- Key systems: Can include master keys, interchangeable cores (IC), and restricted keyways for added control.
ADA Tip: Ensure locks require no tight grasping, pinching, or twisting to operate.
4. Hinges, Pivots, and Continuous Hinges
Purpose: Attach the door to the frame and allow smooth movement.
Types of Hinges:
- Standard butt hinges: Basic, durable, and easy to install.
- Continuous (piano) hinges: Great for high-use doors or doors that sag over time.
- Heavy-duty pivots: Often used on aluminum doors with heavy glass panels.
- Offset and center-hung pivots: For specialty doors like frameless glass or all-glass entries.
Durability Note: High-traffic doors benefit from continuous hinges to distribute weight evenly and reduce stress on the frame.
5. Weatherstripping, Thresholds, and Seals
Purpose: Prevent drafts, water intrusion, and improve energy efficiency.
Types:
- Door sweeps: Mount to the bottom of the door to block air and dust.
- Perimeter seals: Compress or brush-style seals for sides and top.
- Thresholds: Create a smooth transition while sealing the door-to-floor gap.
- Smoke and fire gaskets: Required on many fire-rated assemblies.
Energy Efficiency Tip: Upgrading these components can reduce HVAC loss and improve building comfort.
6. Electronic Access Control Hardware
Purpose: Enhance building security with remote access, time schedules, and audit trails.
Components:
- Card readers, keypads, or mobile access controls
- Electric strikes, magnetic locks, or electrified exit devices
- Request-to-exit (REX) sensors and push-to-exit buttons
- Controllers and software for managing user credentials
Compatibility Tip: Not all door types support all access control systems. Aluminum and steel doors are most common for electrified hardware.
