Tank sticks measure the fuel and water in your underground storage tanks and come in several lengths and styles. One piece wooden tank sticks are the most popular because of their durability. Sectional wooden tank sticks can be disassembled so they are convenient to store and can be shipped via UPS. Both feature black ink printed gallons per inch measuring on two sides with a clear coating for protection. The other sides are painted flat black so the wetness shows up for easy reading. Telescopic sign changers allow you to change sign numbers easily from the ground so you won?t need a ladder. Single and double cup models are available in eighteen and twenty-four foot telescopic lengths.
