Features Heavy-Duty Steel Frame Supports Tripp Lite's Aisle Containment System Two SmartRack® frame kits are required to create a semi-airtight aisle that keeps cold and hot air separated to increase efficiency in temperature control and distribution among the racks. The SRCTMTFRM must also be paired with Tripp Lite's SRCTMTTLBM Beam Kit and SRCTMTSDD Sliding Double-Door Kit (both sold separately). Note: the Aisle Containment System can be configured to be a self-standing unit (tied to racks on both ends) or can be tied directly to a wall at the end of an aisle, no longer needing a second SRCTMTSDD to seal the end. Accommodates Various Server Rack Heights from 42U to 48U The steel frame with black powder-coated finish features pre-drilled mounting holes for the telescopic beam kit (SRCTMTTLBM), making installation efficient and effective, and pre-tapped holes for further fortification. Stabilizing brackets are provided at both feet, allowing the frame to be directly affixed to the floor of your data center. All necessary hardware is included for assembly. Multiple frame kits may be connected together for larger containment arrays. Tripp Lite's Aisle Containment System Manages Airflow for More Cooling Efficiency Upon installation in your data center or server room, the modular, easy-to-assemble Aisle Containment System contains the air in a hot aisle or cold aisle, essentially creating a room within the aisle, while still keeping the aisle accessible. No costly contractor or HVAC specialist is required to install the system, which can be expanded or adapted to meet your needs. Assorted frame kits, beam kits, sliding double-door kits, roof panel kits and adapter riser panel kits (all sold separately) are necessary to assemble a hot or cold Aisle Containment System that accommodates the dimensions of your aisle and the rack enclosures within it.
