VERSATILE JUNCTION BOX SIZED TO HOUSE FOUR STRINGS
Our Junction Box for solar arrays can be deck-mounted or rail-mounted and is specifically sized to house four strings (DC/AC). Deck-mounted installations do not require cutting around the shingles and feature a watertight attic pass-through option. Integrated weep holes, multiple oriented screw bosses, and pre-drilled guides on three sides (South, East, and West) provide a fast, assisted installation.
