Metal brass ring wick holder with a flange width 7/8", overall height 1/4", hole opening 9mm. Brass rings are used with glass wick holders to fit large hole openings. Most of our wick holders have a flange width of 1/2" so to fit a larger opening, a metal brass ring is used and the glass wick holder and wick is placed inside of the brass ring to hold the glass wick holder in place.
Use brass rings with 1/2" flange glass wick holder.
