Safety Neck Candle Sustainers

Wicks Unlimited manufacturers and supplies safety neck candle sustainers with increased neck height enabling candle manufacturers to create tabbed wicks from waxed wick on reels. The safety neck sustainer line includes neck heights of 10.00 mm, 13.0 mm, 13.2 mm, or 14.5 mm, with base diameter(s) of 14.5 mm, 15.0 mm, or 20.0 mm. Since safety neck sustainers feature an extended neck height, the candle’s flame is snuffed earlier during the combustion process. This unique feature reduces the chance of the candle’s container getting hot, especially near its end of life.

Manufacturers can select two crimping options for safety neck candle sustainers: puncture and non-puncture. Wicks Unlimited’s 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’s safety neck candle 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.
