A sliding door locking solution supports research and clinical environments at the University of Southern California.

The University of Southern California (USC) is one of the nation’s leading private research universities, supporting a wide range of academic, clinical, and research programs. Across campus, many interior spaces - including laboratories, clinical rooms, and small meeting areas - are dense with fixed equipment, furnishings, and technology.

In these environments, traditional swing doors can reduce usable floor space, interfere with workflows, and create accessibility challenges. Aspart of ongoing campus upgrades, USC evaluated door hardware solutions that would preserve space efficiency while maintaining durability, safety, and appropriate levels of access control.

BALANCING SPACE CONSTRAINTS WITHSECURITY REQUIREMENTS

While sliding doors offer clear advantages in tight spaces, they also present unique security considerations. Many campus locations required locking solutions that could:

• Support sliding door configurations where swing clearance was unavailable.

• Provide reliable mechanical security in lower-risk areas.

• Deliver electrified, fail-secure access control for sensitive research spaces.

• Withstand high-frequency use with minimal maintenance.

• Integrate cleanly into existing building and access control infrastructure.

USC needed a scalable approach that could accommodate both mechanical and electronic security requirements without introducing unnecessary system complexity.

SOLUTION OVERVIEW

USC selected a combination of INOX mechanical and electrified sliding door locks, deploying each solution based on the functional and security needs of individual spaces.

MECHANICAL SLIDING DOOR LOCKS

For rooms that did not require electronic access control, USC installed INOX PD95 mechanical sliding door locks. These were used primarily in laboratories and meeting rooms where space efficiency was critical, but electronic credentialing was not necessary.

According to USC facilities staff, the PD95 offered several operational advantages:

• Heavy-duty construction designed for institutional use.

• Smooth operation suitable for frequent daily cycles.

• No reported maintenance issues or component failures.

In select locations, double sliding door configurations were implemented. This allowed larger equipment to be moved easily while enabling wider openings for group circulation, without sacrificing the ability to secure the space when closed.

ELECTRIFIED SLIDING DOOR SECURITY

For areas requiring higher levels of security, such as research rooms and spaces protecting personal belongings, USC deployed the INOX PD97ES electrified sliding door lock.

The PD97ES was selected for its integrated design and reliability in mission-critical environments.

Key technical features include:

• Fail-secure operation: The lock remains locked during power loss, protecting assets and sensitive materials.

• Integrated power transfer: Power is delivered directly from the strike to the lock body, eliminating external door loops or concealed transfers.

• Simplified installation: Reduced wiring complexity lowers labor time and minimizes installation errors.

• Compatibility with existing campus access control systems: Designed to integrate with standard credentialing and control platforms.

• Heavy-duty mechanical core: Maintains security integrity even under high usage.

By incorporating power transfer directly into the lock and strike interface, USC reduced long-term maintenance exposure while maintaining a clean door aesthetic, an important consideration in academic and clinical environments.

RESULTS AND PERFORMANCE OUTCOMES

The deployment of INOX sliding door locks delivered measurable benefits across multiple campus facilities:

• Improved space utilization: Sliding doors eliminated swing conflicts, maximizing usable room area.

• Security alignment: Mechanical and electrified solutions were applied based on risk profile, not a one-size-fits-all approach.

• Operational reliability: Both INOX PD95 and INOX PD97ES locks performed consistently with minimal service needs.

• Installation efficiency: Integrated electrification reduced wiring complexity and installation time.

• User confidence: Facilities and access control teams reported confidence in system performance and vendor support.

USC's security group was also pleased with the responsive technical collaboration during specification and deployment.

This project reinforces several best practices relevant to commercial sliding door hardware and security professionals:

1. Sliding doors can be secure when paired with purpose-designed locking hardware.

2. Mechanical locks remain essential in many institutional environments.

3. Integrated power-transfer reduces risk and maintenance headaches compared to external power transfer methods.

4. Fail-secure operation is critical in research and asset-protection applications.

5. Door hardware selection should follow space planning, not the other way around.

PULLING IT ALL TOGETHER

Through the strategic use of mechanical and electrified sliding door locks, USC successfully addressed space limitations while maintaining robust security standards across its campus.

The combination of the INOX PD95 and PD97ES demonstrates how modern door hardware can support flexible layouts, protect sensitive environments, and simplify long-term facility operations.

As universities continue to adapt spaces for evolving academic and research needs, integrated sliding door security solutions offer a proven path forward - delivering safety, efficiency, and reliability without compromise.
