Grommet only — lamp and electrical plug sold separately.
The Peterson B142-18 open-back mounting grommet holds a compatible 2.5-inch round sealed light in a flush-mount installation. Use it to replace the mounting component around a serviceable lamp rather than ordering a complete light kit.
This grommet fits a 3-inch mounting hole. The 2.5-inch size describes the lamp, not the panel opening, so measure the existing opening and compare the lamp model before ordering.
| Feature | Benefit |
|---|---|
| Separate mounting grommet | Replace the mount while retaining a compatible lamp and wiring. |
