Brass Lamp Collars fit onto necks of glass oil lamps to support lamp-burners. Traditionally attached to lamp-neck using plaster-of-Paris. Brass lamp collar has interior threads for a #1 lamp burners to screw into.
The collars are excellent quality. Unfortunately, I cannot use them. They are the wrong size.
This collar for a #1 burner was out-of-stock in most online stores, so I’m glad Paxton had it and shipped it quickly. But, it only has about 1 1/2 revolutions of threads! It needs at least 2 1/2 turns of threads. Had to use plumbers tape to make it usable, but it is still a weak connection. Bought 2 and the other is unusable.
Prompt service, good communication.
The collar was exactly what I needed. However the burner came with it’s own collar which was a modern collar. The burner had coarse threads and would not work in the other collar.
