Abstract
A compounded injection molded plastic grommet including a rigid core and a soft elastomeric overmold defining a body portion with a soft elastomeric tube surrounding a portion of the wiring harness and exposed rigid plastic attachment tabs both fore and aft of the grommet body. The grommet and tube are split to allow side entry of the wiring harness and undercuts are provided at the top and bottom of the grommet for secure attachment to an automotive body structure. Final assembly involves putting the grommet in place and securing the wiring harness to the fore and aft attachment tabs by tape or plastic tie straps or the like.
