    Single-Sided Entry

    Offset Entry

    Plugged and sealed at every opening, these tap/connectors protect wire from groundwater and rocky soil. The trim-to-size port plugs create a tight seal where the wire enters. The other plugs have double O-rings to seal off gaps around the set screws.
    Single-Sided Entry—Insert all your wires from the same side. The slim profile fits better in crowded panels and boxes than dual-sided entry tap/connectors.
    Offset Entry—Attach wires running from opposite directions—especially rigid wire that won't bend around the connector. The connection points are staggered so that current flows freely instead of concentrating in one spot and causing a fault.
    Aluminum and Copper (For Joining Dissimilar Metals)—Aluminum and copper don't play well together, but these connectors keep them in line. They cover the wires with an antioxidant compound so the aluminum wire—and the whole connection—won't oxidize and corrode.
