The ISONAS Trim Kit is typically used when it is desired to mount the PowerNet reader-controller onto a "single-gang electrical outlet box". In some jurisdictions, the local building codes require that an outlet box be used. The use of an electrical outlet box can also localize and simplify the reader-controller's wiring process. Since the opening of a standard outlet box is wider than the width of the PowerNet reader-controller, the Trim Kit is used to completely cover the outlet box, giving the installation a sleek, finished look.
