The standard sizes shown in the table custom models sizes are available or we can provide any fabricated dimensions you may require. In calculating total case sizes, note that the covers are 0.063 inches thick (typical) and should be subtracted from the total height of the case. Also, if standard Modpak connectors are used the minimum case height is 0.75 inches.
All standard covers are 0.063 inches thick and are normally 0.040″ less than the case dimension. Standard mounting is provided via rivnut standoffs which have a tapped bottom for 4-40 hardware. Covers that extend beyond the ends of the unit are available when clearance hole mounting is desired.

To support large PC boards or when additional grounding points may be needed, Modpak offers the option of adding groove pins to your custom unit. A groove pin is a 0.062 inch diameter steel dowel pin which is pressed into the sides walls of the unit. Groove pins are available in 1/4″ and 5/8″ lengths.
