B&K Tank oil tank measuring stick — 4-fold 126" hardwood gauge, calibrated 120", high-contrast markings

The B&K Tank 4-fold oil tank measuring stick is a durable hardwood gauge that folds compactly and extends to 126" for checking fluid levels in underground storage tanks.

Designed for technicians, facility managers, and service crews, this four-piece tank stick combines traditional hardwood construction with clear silver calibration marks for reliable, long-lasting use. Its black-painted finish resists grime while the 10" handling section and foldable design make transport and storage straightforward. Calibrated to 120" and extending to 126", it’s suitable for a wide range of fueling and storage tanks including gasoline, kerosene, and diesel vessels.

How accurate is the measurement on this tank stick?

The stick features precision-printed silver graduations on a smooth hardwood surface, enabling repeatable readings when used correctly. Because it’s a mechanical gauge, accuracy depends on fully extending the sections and observing from the same angle each time.

• Calibrated to 120" with total reach of 126"
• High-contrast silver markings on a black background for visibility
• Solid hardwood minimizes flex compared with cheaper plastics
• Best used when sections are fully locked and vertical for true depth

How easy is it to carry and store on a job site?

The four-fold design collapses into a compact unit with a dedicated 10" handling section that keeps the stick easy to grip. It fits in service vans, toolboxes, or locker compartments without requiring special mounts.

• Folds down into four segments for compact storage
• 10" handling section gives stable grip while measuring
• Lightweight hardwood construction balances strength and portability
• Painted finish resists surface dirt for cleaner transport

What kinds of tanks and fluids can I use this for?

This stick is intended for manual depth readings in underground storage tanks commonly used for fuels and related liquids. It’s suitable for gasoline, diesel, kerosene, and similar products where a calibrated wooden gauge is appropriate.

• Works with underground storage tanks and many above-ground tanks
• Appropriate for gasoline, kero, diesel and non-corrosive liquids
• Not for precise volumetric conversions—use with tank charts or charts
• Use standard safety practices when opening tank access points

How durable is the construction and finish?

Made from quality hardwood and painted black, the stick resists everyday wear and holds calibration marks clearly over time. The silver ink markings are selected for contrast and long-term legibility under typical field conditions.

• Quality hardwood core offers years of service
• Black paint reduces visible soil and staining
• Silver calibration remains readable after repeated use
• Simple, repairable design—replaceable if damaged

Who is this for? The B&K Tank 4-fold measuring stick is aimed at fuel service technicians, maintenance personnel, and facility operators who need a straightforward, rugged tool for checking liquid depths in tanks. If you want a no-frills, mechanical gauge that stores easily in a service vehicle and gives dependable depth readings up to 126", this stick is built to fit that routine without electronics or special training. For tasks requiring precise volume calculations or digital logging, pair this stick with your tank’s calibration chart or a secondary measurement system.
