Lox-On Aladdin Lamp Chimneys have notches in glass base which lock into chimney holder. These Aladdin style chimneys are used in the restoration of Aladdin lamps. The burner on this style lamp has ridges for the lox-on notches to catch on. Lox-on Aladdin chimneys are only used on Aladdin lamps.
I have not ordered a chimney for many, many years. This is exactly what I needed to complete my lamp project. If I would need another....I will definitely order again.
