In a method for inserting a grommet into a structural member, a grommet slot is provided that opens into a grommet hole. The grommet slot is accessible in a plane of the grommet hole at an access location spaced from the grommet hole and has a closed-off end remote from the grommet hole. The grommet is compressed to a size allowing insertion into the grommet slot at the access location. The grommet is inserted into the grommet slot at the access location and pushed into the grommet hole. The method can be done manually or by automation.
