In the fast-paced world of data centers and enterprise IT, where space is premium and downtime is disastrous, rack-mountable solutions are non-negotiable. The APC Smart-UPS RT 19″ Rail Kit (SRTRK2), designed specifically for Smart-UPS RT models in the 3kVA, 5kVA, 6kVA, 8kVA, and 10kVA range, transforms versatile tower UPS units into seamless rack integrations. From Schneider Electric’s APC lineup, this accessory ensures secure, adjustable mounting in standard 19-inch EIA racks, optimizing airflow and accessibility. As of September 2025, with data center densities soaring amid AI and edge computing booms, the SRTRK2 remains a go-to for IT pros seeking flexible, scalable power protection. In this blog, we’ll unpack its features, specs, applications, and why it’s a must-have for modern infrastructures.
Key Features: Simplicity Meets Robust Design
The SRTRK2 isn’t just brackets—it’s a thoughtfully engineered kit that bridges tower flexibility with rack efficiency. It supports easy conversion of APC’s Smart-UPS RT series, allowing users to deploy high-capacity UPS systems without custom fabrication. Highlights include:
- Universal Compatibility: Tailored for Smart-UPS RT 3/5/6/8/10kVA models, ensuring a precise fit for these double-conversion online UPS units that deliver zero-transfer-time power.
- Adjustable Mounting: Telescoping rails accommodate various rack depths (up to 32 inches / 813 mm), with quick-release latches for slide-in/out access—ideal for maintenance without full rack disassembly.
- Cable Management Integration: Built-in strain relief and routing channels keep power and network cables organized, reducing clutter and improving cooling in dense environments.
- Tool-Less Installation: Snap-and-lock design minimizes setup time, with included hardware for both front and rear rack posts. No specialized tools required, making it accessible for field techs.
- Durable Construction: Powder-coated steel rails resist corrosion and vibration, supporting loads up to the UPS weight (typically 100-200 lbs for these models) while maintaining structural integrity.
These features embody APC’s focus on user-centric design, turning potential installation headaches into a straightforward process.
Technical Specifications: Precision Engineering for Rack Environments
The SRTRK2 is compact yet sturdy, fitting seamlessly into 19-inch racks without wasting U-space. It’s optimized for the Smart-UPS RT series’ modular architecture, supporting both standalone and extended-runtime configurations.

The kit’s low profile (occupies no additional rack units beyond the UPS) and compliance with UL, CE, and RoHS standards ensure it’s ready for global deployments. For deeper rack needs, pair it with APC’s optional shelf kits if hybrid mounting is required.
Ideal Applications: Elevating Rack-Based Deployments
The SRTRK2 shines in scenarios where rack space optimization and quick scalability are key:
- Mid-Sized Data Centers: Mount 5-10kVA UPS units alongside servers and switches, enabling hot-swappable batteries and remote management without floor space trade-offs.
- Edge Computing and Telecom Hubs: Secure power protection in shallow racks for distributed sites, supporting VoIP and networking gear in constrained cabinets.
- Branch Offices and Colocation: Convert tower UPS for standard 19-inch racks in shared facilities, facilitating easy relocation and integration with existing infrastructure.
- Hybrid IT Environments: Ideal for organizations transitioning from tower to rack setups, especially with APC’s EcoStruxure IT for centralized monitoring.
Resellers in 2025 note its popularity in EMEA and APAC regions, where rack standardization is accelerating. It’s a fraction of the UPS cost but unlocks full rack potential.
Why Choose the SRTRK2? Streamlined Efficiency and ROI
Investing in the SRTRK2 means more than mounting—it’s about enhancing overall system reliability and reducing operational costs. By enabling rack deployment, it improves airflow (reducing cooling needs by up to 15%) and simplifies cable management, cutting maintenance time by 30-50%. Its compatibility with APC’s intelligent battery modules extends runtime without reconfiguration, while the 2-year warranty aligns with enterprise standards.
User feedback from IT forums and resellers praises its “effortless install” and durability—one 2025 review highlighted seamless integration in a 10kVA setup, noting zero compatibility issues. Compared to universal rail kits, the SRTRK2’s APC-specific design avoids fitment pitfalls, making it a no-brainer for Smart-UPS RT owners. In an era of space-constrained data growth, it future-proofs your power strategy.
