Aisle Containment System keeps hot and cool air separated for better temperature control and equipment performance in hot aisle/cold aisle configurations.FeaturesSecurely Locks Down a Rack Aisle, While Trapping Either Cold or Hot Air Within These SmartRack® heavy-duty double doors install with the Tripp Lite aisle containment system, enabling you to easily access a contained aisle, while also closing it off to avoid airflow contamination. The doors provide a semi-airtight seal at the end of a contained aisle, trapping either cold or hot air inside to increase efficiency in temperature control and distribution among the racks. Adjustable ball bearing rails and brushed door bottoms allow the doors to slide open and closed smoothly.Designed to Keep Your Mission-Critical Rack Components Safe The sliding doors lock securely with the included keys to deter tampering, damage or theft. Clear acrylic windows let you keep an eye on the aisle's contents without having to unlock the doors and step inside. This double-door kit is only compatible with Tripp Lite's SRCTMTFRM Frame End Kit (sold separately), which has pre-tapped holes designed for attaching the doors.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.
