class=\"disclaimer-block\"\u003eThe enclosure recommendations listed above are external dimensions which assume the use of 0.75 in (19 mm) thick material. If you are using 0.625 in (16 mm) thick material, subtract 0.25 in (6.5 mm) from each dimension. Do not use any material with a thickness of less than 0.625 in (16 mm) as this may compromise the rigidity of the enclosure.\u003c\/p\u003e\n\u003cp class=\"disclaimer-block\"\u003eAll enclosure volumes listed above are net internal volumes!
