Description

Galvanized Steel: Made of high-quality anti-rust galvanized steel, it features excellent corrosion resistance and an ultra-long service life.

Fire Resistance and Flame Retardancy: The metal material provides high-grade fire protection and effectively suppresses fires caused by electric arcs or short circuits.

Multi-purpose Knock-out Holes (KOs): Preformed round holes of different sizes are arranged around and on the back of the enclosure. Simply pry them open gently with a screwdriver to freely route electrical conduits of various diameters.

Extra Large Internal Space: The square design offers more cubic inches of volume than round or octagonal boxes of the same size. It can easily accommodate multiple switches and sockets, and allows thick wires to bend and fold neatly inside the box.

Exclusive Green Grounding Screw: Equipped with a bright green protruding grounding screw at the bottom, it enables fast and standard ground wire connection to ensure electrical safety.

Multiple fixing mounting holes: The bottom of the box is reserved with multiple screw fixing holes, enabling firm installation on wooden keels, light steel keels or concrete walls.

Diagonal Mounting Tabs: Pre-installed screw mounting tabs on the edges allow direct installation of various Mud Rings, industrial enclosures or standard panels.
