Enclosure Keyboard Shelves & Trays

Hoffman CONCEPT Keyboard Boxes are self-contained, external Type 4 housings for a keyboard, that fits on an outside surface of an enclosure. A large hole and rubber plug are provided for keyboard cords. A right and a left mouse tray slides out from under the keyboard mounting surface.
Hoffman PROLINE-PC Keyboard Shelves allow two options for mounting keyboards. A standard keyboard can be placed in the recessed side or a membrane-type keyboard can be placed on the flush side. The recessed side has a 5 degree angle from horizontal, while the flush side provides a 12 degree angle.
Hoffman PROLINE-PC Keyboard Compartments are self-contained, sealed modules that mount to an accessory front opening. The aluminum, hinged door is lockable and has pushbutton latches. PC keyboards rest on a ball-bearing glide shelf with a soft palm-rest. Seamless foam-in-place gasket on the door assures a dust-tight seal.
Hoffman Pivoting Keyboard Shelves with Mouse Tray mount either in a 19 inch open-frame rack or in a cabinet. The shelves pull out and pivot 90 degrees to access full-size keyboards. The shelves allow keyboards to slide between standard rack angles and include a mouse tray. The keyboard tray extends 9.75 inches beyond the front of the open-frame rack or rack angles.
Hoffman Aluminum Keyboard Compartments provide a convenient way to incorporate a keyboard with other 19 inch rack-mounted equipment. The compartments are made of lightweight aluminum and accommodate keyboards up to 16.5 inches wide.
Products
Common modifications or accessories that are used to enhance electrical cabinets.
Lighting kits. Lighting kits are often used in outdoor applications. There are many different styles of lighting kits that can be used, but LEDs have become the preferred lighting solution in the past several years.
Pressure switches. Pressure switches operate on a spring and react to the cabinet door opening and closing. They can be used for lights, intrusions alarms and exhaust fans.
Passive air vents. Passive air vents allow natural air circulation to flow through a cabinet providing proper ventilation.
Enclosure fans. Enclosure air fans are used when more ventilation is required. The size of the fan will depend on the size of the enclosure as well as the amount of air that needs to be circulated.
Air conditioners. Air conditioners are used when ambient air circulation is inadequate to cool the cabinet. The air conditioner size will depend on the enclosure size, ambient air temperature and heat generated within the cabinet.
Heaters. Heaters are used when a cabinet is located in areas that may be exposed to cold temperatures.
Locking mechanisms. Locking mechanisms are used to secure cabinets.
Conduit hole seals. Conduit hole seals are used on cabinets that have holes that need to be plugged after conduit has been removed.
