Product Description
Tank Accessories: Spiral Side-Reading Dial Level Gauge Gives Instant Tank Level Checks From 18″ to 26″ Tank Heights. Made in the USA by AMERICAN TRUCKBOXES ATB®️
The TGLS spiral side-reading dial level gauge is built for fleet operators and tradespeople who need a fast, accurate read on tank contents without guesswork. Its side-view fractional dial lets you check fuel, DEF, or fluid level at a glance instead of climbing up to sight-check a tank. American Truckboxes LLC manufactures this gauge in Blanchard, North Dakota, backing every unit with the same heavy-duty standards used across the ATB product line. The gauge is offered in four tank heights, so fleets running mixed tank sizes can standardize on one reliable gauge design.
