A 2-inch rubber grommet plug closes a specified unused opening. Two inches equals 50.8 mm; confirm whether that label refers to the mounting hole or another feature.
Check the panel-thickness range, retaining profile and flange clearance. If a cable must pass through the opening, use a suitable open or purpose-made sealing profile rather than an ordinary blind plug.
Select the compound for the actual temperature, fluids and weather exposure. Aging and ultraviolet exposure can affect rubber, so follow the product's inspection requirements. Verify retention and any required seal after installation.
