Eaton SR45UBDP48 Tripp Lite 45 U Extra Deep Server Rack Enclosure

SR45UBDP48Overview

The Eaton SR45UBDP48 is a 45-unit tall cabinet built for those scenarios where standard-depth racks no longer suffice—think full-depth servers, large UPS systems, heavy cable bundles or rear-mounted power modules. With an internal usable depth of 48 inches (≈1219 mm) it gives you space behind the rails for service access, airflow and cable exits.It comes fully assembled with pre-installed heavy-duty steel, powder-coated finish, locking front/rear doors, removable locking side panels and pre-installed casters for quick roll-in. The heavy duty build supports a stationary load capacity of up to 3 500 lb (1 588 kg) and rolling load up to 2 250 lb (1 021 kg) when being moved into position.Vented doors and top access ports enable front-to-rear airflow, and the side panels and bottom opening support clean cable routing and tidy installations helping maintain air-management integrity in dense racks. In real-world use you’d pick this cabinet when installing deep servers (>1 000 mm), multi-bay storage shelves with rear-mounted PSUs, vertical PDUs behind equipment, or when you expect heavy cabling or expansion. Its extra depth future-proofs the rack footprint while preserving the 45 U height standard.
