Knot Filler Gun

Heavy-duty gun for applying Knot Filler rods


This heavy-duty heating gun is a popular choice for applying Knot Filler rods or sticks form. While it's right for the job, it's not your only option- most adjustable temperature hot-glue guns can be used. There are two requirements of your dispensing gun: Our rod's diameter is 12mm (a little less than 1/2") with 295mm (about 11") in length, and there are three melting points depending on the rod used. Please refer to our Knot Filler Rods' colors and melting points chart. If in your shop, you already have a gun that fits these two requirements, try it out with a sample or single color pack. And if you are a higher volume user, or if you need to switch color often, you may want to get an additional gun to minimize labor and material waste. The actual color of the gun sold may vary.
