When your installation demands maximum weather sealing and panel visibility is not a requirement, the STI EF201610-O delivers. At 20 in. H x 16 in. W x 10 in. D, this is the largest opaque enclosure in the EF201610 series. The "O" suffix confirms a solid door with no window cutout and no fan penetration, giving you the most complete barrier against rain, dust, and corrosive environments.
The EF201610-O is ideal for protected outdoor locations where temperature buildup is not a concern — covered equipment rooms, conditioned spaces with exterior walls, or installations in milder climates. The large interior accommodates full-size fire alarm control panels, power supplies with battery backup, and ancillary life safety equipment.
