Sometimes the simplest solution is the right one. The STI EF181610-O is a no-frills, fully sealed enclosure: 18 in. H x 16 in. W x 10 in. D, solid opaque door, no window, no fan penetrations. The "O" suffix tells the story plainly — this is a weatherproof fiberglass box that keeps everything out.
It is well-matched to installations in moderate climates or protected locations where the equipment inside does not generate significant heat. Think covered exterior walls in mild coastal cities, interior-facing outdoor niches in commercial buildings, or retrofit projects where an existing conduit layout makes a simple sealed enclosure the path of least resistance. The fiberglass shell of the EF181610-O will not rust, pit, or corrode in humid or salt-air environments where steel enclosures fail prematurely.

- Door style: Solid opaque, no penetrations
- Material: UV-resistant fiberglass
- Rating: NEMA 3R weatherproof

The STI EF181610-O is a clean, cost-effective choice for sealed outdoor installations. Verify equipment dimensions before ordering.
