Save your fingers! Let this simple tool do your heavy squeezing for you. Effortlessly dispense even the thickest sealants including Hylomar (Part No. 3300) or Blue RTV Silicone (Part No. LT-58730) without bruising your fingertips. The comfortable pistol-grip handles give you precise control -- no more sudden globs, which means less waste. The flat gripping plates squeeze the tube from the bottom, ensuring that you get every last bit that you paid for! Sealants sold separately. Get one for each tube in your toolbox. Great for toothpaste too!
