Hoffman Modular Enclosure Frames & Racks

Frames and Racks consists of metal forms with with pre-drilled holes that are spaced at standardized units of measurement that will accommodate common accessories that can be added to the interior or exterior without drilling or welding. Modular frames can be joined to one another, creating the possibility of multiple configurations, and rails can be added to the frame making it possible to slide panels into and out of the enclosure from the front, rear or side openings. 

Hoffman PROLINE G2 frames protect components inside this line of modular enclosures. The frames were designed to withstand heavier load requirements and to provide a solid foundation for the electrical enclosure.

Hoffman PROLINE G2 disconnect frames can be used with PROLINE G2 disconnect doors and components to configure a custom disconnect enclosure from standard enclosure components.

Hoffman PROLINE G2 heavy-duty swing-out rack frame allows 19 inch rack panels or equipment to pivot for better accessibility. The center pivot provides a 350 degree rotation with a 400 pound load rating. Right or left offset options allow the frame to pivot out of the enclosure and are capable of 140 degree rotation.

Hoffman PROLINE G2 full access rack is a design adaptation of the heavy-duty swing-out rack frame, serving a similar function, but allows the rack frame to swing out of the enclosure for full access to the 19 inch rack equipment. The full access rack has been rated to a 300 pound load capacity.

The PROLINE G2 Rack Angles Plated and furnished in pairs mount using BV-M6 fasteners instead of the traditional cage nut and screw combination. The Rack Angle height and rack unit count are optimized for the PROLINE G2 frame heights. Rack Angles have two mounting surfaces that function in the attachment of rack-mount equipment and accessories. Can be mounted directly to the frame, or at variable depths using Adjustable Rack-Mounting Rails or Grid Straps; when mounted to the frame there is 44mm between the door opening and the Rack Angle mounting surface. Single-bay Frames: in a 600-mm wide frame, Rack Angles can be mounted in-line with the frame; in an 800-mm wide frame, Adjustable Rack-Mounting Rails or Frame Reducing Brackets are required (sold separately) to achieve the 19" rack spacing Double-Bay Frames: in a 1200-mm wide frame, Center Uprights must be used to create a mounting surface in the center of the enclosure for either bay; in a 1600-mm frame, Center Uprights are again required in addition to Frame Reducing Brackets or Adjustable Rack-Mounting Rails to achieve the 19" rack spacing Tapped-Hole Rack Angles are 12 gauge (2.5mm) steel and accommodate 10-32 screws for equipment mounting. Square-Hole Rack Angles are 14 gauge (1.75mm) steel and accept both metric and English cage nuts and screws: most commonly M5, M6, and 10-32 screws. Optional Shelves, Drawers, and Guides require two sets of Rack Angles to secure within the frame. All mounting hardware for Rack Angle installation into the frame is included; mounting hardware for securing rack-mount equipment/accessories to the Rack Angles is either supplied with the item or purchased separately.
