What Makes Duplex Chimneys Special?

Duplex burners use two flat wicks side-by-side, producing significantly more light than single-wick burners. The oval bulge design of this chimney is specifically engineered to accommodate the wider flame pattern of Duplex burners, ensuring proper airflow and optimal combustion. This authentic design detail is essential for safe, efficient operation of your Duplex lamp.

Royal Craft Excellence:

Royal Craft lamp chimneys are manufactured using premium borosilicate glass - the same heat-resistant glass used in laboratory equipment. This advanced glass formula creates chimneys that resist thermal shock, preventing cracks when the lamp heats up or cools down. The result is a chimney that's light, strong, colorless, and built to last for generations.

Perfect For:

• Victorian Duplex oil lamp restoration
• Antique flat wick lamp collectors
• Emergency preparedness lighting
• Off-grid living
• Replacement for broken Duplex chimneys
• Period-correct lamp restoration
• Non-electric ambient lighting

Whether you're restoring a family heirloom, maintaining your collection, or preparing for emergencies, this authentic Duplex chimney provides the quality and performance your vintage lamps deserve.
