  • Plug for sealing more than one size of hole
    Patent number: 6494463
    Abstract: A plug for sealing holes includes a body and at least three sealing ribs. The body is preferably hollow to save material and molding cycle time. A thickened area is formed at a rear of the body such that a screw driver may be used to insert the plug into a hole. The first sealing rib is formed at substantially a front of the body such that a lead-in area is formed on the body to facilitate easy insertion of the plug into a hole. The distance between each sealing rib is at least twice the greatest thickness of a single sealing rib.
