Our solid brass smoke bells are placed above yourwall mounted oil lamps and will capture most of the heat rising from the 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.
Fits all models of 584 A Wall Lamps. Center of smoke bell is 3.75″ from wall.
NEVER touch the smoke bell while the lamp is burning! It will quickly become very hot once the lamp is lighted!
