2.1 1BHousing
The DL8000 uses either of two external housings:
 A cast aluminum casing with stainless steel front cover bolts. It is
flame-proof (in accordance with Class I, Zone 1, Group IIB) and
weatherproof (in accordance with IP66).
 A 14-gauge stainless steel box with 12-gauge stainless steel
mounting flanges, CSA-rated as a Type 4 enclosure. The door is
made of 0.090 inch thick aluminum secured to the box with a
stainless steel piano hinge and two stainless steel spring latches.
