The A Style GrayBox consists of six parts (front panel, rear panel, two sides, top cover and bottom cover) plus hardware. Front and rear panels are different, as are top and bottom covers. The extruded parts, shown below, convey the strength and ruggedness of the GrayBox design as well as show specific details.
Front Panels
Front Panel (Type 1) is distinguished by a plain exterior surface void of detail. Being flat, it is ideally suited for silk-screening. It contains the rack mounting holes and is easily machined. The upper flange supports the top cover and accommodates the fastening screws. The lower track supports the front edge of the captured bottom cover.
Front Panel (Type 2) is distinguished by a flat exterior surface with grooves top and bottom which help frame the panel. As with Type 1, it is easily machined and ideally suited for silk-screening. The upper flange supports the top cover and accommodates the fastening screws. The lower track supports the front edge of the captured bottom cover.
Front Panel (Type 3) is distinguished by a flanged exterior surface similar to that of the B and P Styles. Although it can be silk-screened, it is ideally suited for overlays. Two accompanying spacers which compensate for the recessed surface and allow for rack mounting, complete the framing of the panel. Otherwise, the features are identical to Types 1 and 2 above.
Rear Panels
Rear Panel is made from the same extrusion as the Front Panel (Type 1). It differs in that it is shorter (excluding the rack mounting holes). It is easily machined, and ideally suited for silk-screening. The upper flange supports the top cover and accommodates the fastening screws. The lower track supports the rear edge of the captured bottom cover.
Side Panels
Sides are made from rugged aluminum extrusion. They are easily machined and contain the screw slot detail which allows the front and rear panels to be assembled to them. The upper recess accommodates the stiffening flange of the top cover. The lower track supports the captured bottom cover.
Vented Side Option
Sides are available with a standard ventilation pattern. Refer to the A Style Technical Data Sheet for specifics concerning slot size and location. In rack mount applications, sideways airflow is often the most efficient and unobstructed.
Captive Fastener Option
Captive nuts can be substituted for the standard speednuts. This eliminates the possibility of speednuts falling off and getting lost, and provides a means of electrically grounding the side plates.
Covers
The bottom cover is captured on all sides and recessed to allow mounting components up to a size 6 (or M3.5) pan head screw (eliminating the need for countersinking). The formed top cover with stiffening flanges along each side, screws on from above.
