Wicks Unlimited manufactures and supplies six (6) unique 6.0 mm standard neck metal wick sustainers that enable candle manufacturers to create tabbed wicks from waxed wick on reels. Standard neck 6.0 mm candle sustainers are available with 15.0 mm or 20.0 mm base diameter(s) for easy gluing. Often found in pillar and container candle systems, 6.0 mm sustainers are available with either puncture or non-puncture crimping. Wicks Unlimited best-selling metal candle sustainers with puncture crimping enable manufacturers to develop candles that consume all the fuel (wax) at the end of life. Alternatively, sustainers with non-puncture crimping will extinguish the flame as soon as it reaches the top of the neck and leaves unconsumed wax at the end of life. All of Wicks Unlimited metal candle sustainers, including 6.0 mm sustainers, are manufactured from the highest quality .010″ (0.254 mm) thick tin-coated steel that helps inhibit corrosion caused by fragrance and essential oils and are preferred by candle manufacturers worldwide.
