    Chatsworth Products, Inc., the industry leader in providing solutions for organizing, storing and securing electronic components used in the data and telecommunications industries, now adds the SlimFrame C-series cabinets to its product line. The SlimFrame C-series Cabinet provides unparalleled quality in the areas of design, construction, materials, and workmanship.

    The award-winning MegaFrame® is now available in a narrower footprint. The SlimFrame, designed and offered with CPI Style in mind, assures that mission critical hardware is safe and secure in a package conveniently corresponding to the standard raised floor tile width. Even without a raised floor environment, if space is at a premium and cable management is not an overriding issue, the SlimFrame supports requirements to stack more file servers per row of cabinets. The SlimFrame cabinet system provides an ideal storage solution for EIA standard 19” rack-mountable equipment and is configurable to meet a wide variety of application requirements. The cabinet can bay to any existing MegaFrame to meet the demand for data storage expansion. Multiple SlimFrame cabinets can easily bay together by selecting variations without side panels and using the included multi-bay attachment hardware kit. Bayed cabinets or frames can accommodate the patent-pending MegaFrame vertical cable management ring sections. Three depths are offered: 22", 30" and 36", as well as three height options: 84", 78", and 72". A variety of door styles are available to support different thermal management and security requirements. Standard quick-release doors make it easy to customize the cabinets for doors to open from either the right or left.

    Made from 6061-T6 high-grade aluminum and 6063-T5 high strength aluminum extrusion, the SlimFrame C-Series Cabinet System delivers rugged durability and good looks in a lightweight, easy-to-handle package. A 1000 pound static load rating and 24" width equals more file servers per square foot of data center floor space.

    The SlimFrame can be utilized as a standard four-post cabinet, or, as a two-channel rack by simply sliding the mounting rails together. To create an Open Architecture System, purchase the basic frame without doors, side panels and top.

    A full range of accessories is available to complement and integrate with the SlimFrame C-series Cabinet System. Accessories include a fan kit, sliding shelves, caster set, and vertical mounting rails. Please refer to the product catalog for a full listing and additional product offerings. Ships fully assembled.

    The award-winning MegaFrame Cabinet is now offered in a seismic-rated cabinet solution. Rated Zone 4 compliant to Bellcore GR-63-CORE for Network Equipment Building Systems (NEBS), Section, the Seismic FrameCabinet System is able to withstand the seismic stress of an 8.3 Richter scale earthquake.

    Offered in a 19" w x 36" d x 84" h cabinet solution, the aluminum outer frame provides the sound structural environment necessary for sensitive Information Technology (IT) hardware components. With Multi-Mount™ rails, the cabinet fulfills various rack-mounting requirements.

    The heart of the Seismic Frame Cabinet System is a reinforced inner frame that provides increased structural rigidity. The cabinet system is certified to an 800 lb equipment load in a seismic environment.

    The Seismic Frame Cabinet has built-in cable management via an aluminum top panel with four edge protected punch-out ports. Three inches of space between the side panel and interior cabinet houses two vertical cabling ring sections which accommodate interior cable management. In data centers using raised floor cable routing, the Seismic Frame’s open base easily addresses the maintenance of cables for entry and exit while providing optimal top to bottom ventilation for the interior cabinet. For maximum thermal management, the cabinet features a vented plexiglass front door and a perforated metal rear door. Ships fully assembled.

    The T-Series SteelFrame Cabinet is CPI’s standard server cabinet offering a high quality and fully featured solution for storing computer, data storage, networking and security equipment in data centers, equipment rooms and network facilities.

    CPI’s T-Series SteelFrame Cabinet is available in three styles: T-Series SteelFrame Frame Only, T-Series SteelFrame Cabinet and T-Series SteelFrame with Vertical Exhaust Duct. The T-Series SteelFrame Frame Only offers sturdy, open support for equipment up to 44” deep (1120 mm). The T-Series SteelFrame Cabinet provides additional physical security and airflow management by including a top panel with a choice of side panels and doors. The T-Series SteelFrame Cabinet with Vertical Exhaust Duct is for high heat density applications. The duct isolates hot exhaust air from the room as it exits the top of the cabinet to improve cooling system performance.

    The T-Series SteelFrame features a stylish perforated (mesh) metal front door with 63% open area and a swing handle latch with a keyed lock for added security. Solid metal, plexiglass and fan door options are also available. All T-Series SteelFrame doors can be easily removed, reversed to open from the right or left and can be exchanged between the front and rear of the cabinet. The cabinet is designed with an open base and a top panel that offers edge-protected cable access ports. To block airflow through the base of the cabinet, a Bottom Panel Kit is available as an accessory.

    Cabinets are available in a narrow (T1) or wide (T2) footprint. The narrow (T1) footprint maximizes floor space and fits over 24" wide (610 mm) raised access floor tiles, while the wide (T2) footprint provides approximately 3" (75 mm) of internal cable management space along both sides of equipment. All T-Series SteelFrame Cabinets include a vertical cable manager and two pairs of threaded or square-punched 19” wide, EIA-310-D compliant, adjustable-depth equipment mounting rails that provide front and rear support for equipment and shelves.
