MacMall - Your #1 Apple Superstore

Built For Your Convenience

With a design streamlined by years of customer feedback and IT best practices, SmartRack enclosures make your job easier. Enclosures ship fully assembled for rapid deployment and roll into place on heavy-duty casters. Toolless mounting slots allow quick installation of PDUs and vertical cable managers. Adjustable mounting rails include an easy-view depth index to eliminate time-consuming measurements. Lightweight modular doors and side panels provide safe, convenient service access. Integrated baying tabs facilitate combining enclosures in rows for standard data center baying applications.

Ideal For High-Density Data Centers

Heavy-duty SmartRack enclosures hold up to 3000 lb (1363 kg) and support advanced cooling, cable management, power distribution and monitoring features that keep critical servers and network equipment operating nonstop. Perforated doors permit massive front-to-rear airflow that exceeds server manufacturer requirements. SmartRack enclosures are fully compatible with hot-aisle / cold-aisle data center configurations. Airflow optimization accessories prevent air recirculation that compromises cooling efficiency.


SmartRack Enclosures Grow With You

Applications like hosting, colocation and server farms often experience rapid growth, requiring you to install deeper server chassis that pack more processing power in each rack enclosure. Replacing standard enclosures with deeper models is expensive and time-consuming, but Tripp Lite's rack enclosure extension frame (model SREXTENDER, sold separately) allows you to increase mounting depth by 8” (203 mm) without replacing enclosures or reinstalling existing equipment. You can add SREXTENDER to 48U, 42U or 25U SmartRack enclosures at any time, giving you room to grow without increasing your up-front investment.



SREXTENDER allows SmartRack enclosures to house deeper equipment, avoiding expensive and timeconsuming enclosure replacement. The toolless mounting rails fit inside the extension frame, accommodating vertical cable managers and PDUs. Maximum mounting depth increases from 35.75" (908 mm) to 43.75" (1111 mm).

SmartRack Enclosure Features:

Adjustable Mounting Rails (4) with Easy-View Depth Index

Modular Side Panels (Lockable/Removable)

Front and rear sets of rails adjust in ¼” (6.4 mm) increments. Adjustment is quick and convenient – simply unscrew the rails, slide them to the desired depth and restore the screws. The easy-view depth index ensures consistent rail placement without requiring time-consuming measurements. Square mounting holes and included hardware (not shown) support standard 19” (482.6 mm) rackmount installation

Modular side panels are smaller and lighter, improving ease of installation and service. Standard 25U models include two side panels. Standard 42U and 48U models include four side panels. Side panels are not included with “EXP” models, which are intended for in-row baying and other applications that do not require side panels

Toolless Mounting Rails (2) with Easy-View Depth Index

Baying Tabs (2)

Baying tabs allow enclosures to be combined securely in rows. Center-to-center width can be set at 600 mm or 24” to match standard data center floor tiles.

Adjustable rails include toolless mounting slots for quick installation of compatible PDUs and cable managers. The easy‑view depth index ensures consistent rail placement without requiring timeconsuming measurements. Mounting slots are arranged in an industry-standard pattern compatible with a wide variety of accessories. Each rail can accommodate two vertical PDUs or cable managers side-by-side (four per enclosure).

Heavy-Duty Casters and Levelers (4 each)

Casters support a rolling load capacity of 2250 lb (1022 kg), allowing enclosures to be pre-configured and rolled to the final installation location. Levelers support a stationary load capacity of 3000 lb (1363 kg) and adjust to improve enclosure stability. Casters and levelers are removable

Roof Panel (Removable)

Spring-loaded pins allow the roof panel to be removed and replaced in seconds. Includes cable access channels and mounting slots for cable management accessories.

Convenient Grounding System

All components are grounded to the enclosure frame, which includes multiple connections for facility ground. Front and rear doors include quick-release ground wires for convenient configuration.

Front Door (Lockable/Removable/Reversible)

The door is perforated for optimal airflow, which exceeds server manufacturer requirements. The door handle is reversible to preserve standard orientation if the door is reversed.

Stabilizing Brackets (2)

The included stabilizing brackets are used for shipment and can be attached at the bottom of the enclosure frame (inside or outside) to improve stability after installation. The brackets can be bolted to the floor with the addition of the optional SRBOLTDOWN kit. For maximum enclosure stability, add the optional SRSTABILIZE anti-tip stabilizing plate kit

Split Rear Doors (Lockable/Removable)

Split rear doors reduce clearance requirements for service access. The doors are perforated for optimal airflow, which exceeds server manufacturer requirements.
