TABLE OF KOSMOS PARTS
This is a table of the dimensions of kosmos burner parts. The inside diameter of the collar is the side-to-opposite-side distance of the threaded portion on your lamp (called a collar). The bottom o.d. of the burner is the same since it threads into that collar opening. If your lamp is missing a collar, select a collar that will fit over and conceal the neck of the oil font. Normally these are secured by an adhesive that dries hard such as plaster of Paris, acrylic caulk, tile grout, or similar.
Note that the collar for the #12 burner and #14 burner are identical. The #12 is a smaller burner with a smaller wick, but has the same size threaded bottom as the #14 burner.
