Expanding Lamp Collar, #1 to #2

This expanding collar adapts your existing lamp by threading into a standard #1 collar opening and enlarging the top to accommodate a #2 burner. Since #1 burners have become difficult to source, this adapter lets you breathe new life into vintage lamps by upgrading them with readily available #2 burner options—a practical solution for keeping cherished fixtures functional.
