Safety Neck Candle Sustainers

Wicks Unlimited manufacturers and supplies nine (9) unique safety neck candle sustainers with increased neck height that enable candle manufacturers to create tabbed wicks from waxed wick on reels. All of our safety neck sustainers are manufactured from .010” (0.254 mm) thick tin-coated steel that helps inhibit corrosion and are preferred by leading candle manufacturers worldwide. Wicks Unlimited safety sustainer series includes sustainers with neck heights of 10.00 mm, 13.0 mm, 13.2 mm, and 14.5 mm. The base diameters range from 14.5 mm to 15.0 mm for easy gluing. Since safety neck sustainers feature an extended neck height, the candle’s flame is snuffed sooner during the combustion process. This unique feature reduces the chance of the candle’s container getting hot, especially near its end of life.

Candle manufacturers can select two crimping options for in-house cut and tab production runs: puncture and non-puncture. The puncture crimp creates several small and one large piercing in the sustainer’s wall while still providing a tight wick grip and increasing the crimp’s overall tensile strength. Wicks Unlimited’s proprietary non-puncture crimping option enables candles to “shut off” at the end of life and will meet or exceed all standard operating requirements for crimp hold. The sustainer’s height and crimp determine the container’s base thermal profile, indicating an aggressive or a conservative system and the remaining amount of wax at the candle’s end of life.

Glossary of Terms


Measured in yards of wick per pound in weight. The higher the yield, the smaller the wick and the flame and the resulting heat generated.


The rate of wax consumption in ounces by the wick in one hour. The higher the burn rate the more wax which is being consumed. Used to determine how well a wick and wax combination is performing.
