Our solid brass smoke bells are placed above your wall lantern and will capture most of the heat rising from the wall kerosene oil lantern so there is little danger of whatever it is suspended from, getting over-heated. Somehow if black smoke occurs it will also absorb and divert it and save you lots of time in clean up. NEVER touch the smoke bell while the lamp is burning! It will quickly become very hot once the lamp is lighted!
Fits models 9920A "Mansfield" and "Dorset" 9891A-WM series wall mounted oil lamps. Center of smoke bell is 3" from wall.
