Enclosure without Handle Cutout Enclosures with a Flange Thickness less than 3/6" use dimensions below to install disconnect handle. Enclosures with a Flange Thickness 3/6" and greater use dimensions in alternate Mounting Kit 494V-H3 to install disconnect handle. Multi-Door Enclosures may require the need for a more rigid flange / mounting plate system, such as a Channel Support Kit. Use dimensions in Channel Support Kit 494V-H5, if handle is mounted on top of the channel. Locate Handle C C Top Handle Hole Right Hand Flange Left Hand Flange Drill Handle Holes ().65 Dia.
