For applications such as computer room, tunnel or other low-ventilation areas, specify a smokeless ERICO CADWELD EXOLON mold. Add an XL prefix to the standard mold part number when ordering (for example, a TAC2Q2Q becomes XLTAC2Q2Q). Similarly, ERICO CADWELD EXOLON welding material is also designated by the XL prefix (for example, 150 becomes XL150).
A gap between conductors may be required. See mold tag for more information.
