1.DUAL HEAD & 12.7-INCH EXTENDED DESIGN: Features a straight foot chuck (inner wheels/RVs/semi trucks) and 30° reverse chuck (outer wheels), ideal for dual-wheel setups on 18-wheelers, commercial trucks, and RVs. The 12.7-inch length provides easy access to hard-to-reach valves on tall trucks, RVs, and dually Tires. 2.ACCURATE DUAL SCALE READINGS:Two-side Aluminum bar calibrated in 10-150 PSI (2 psi increments) and 1-10 Bar, with large, easy-to-read printed scales. Analog design requires no batteries, making it reliable for heavy-duty use and harsh environments. 3.INDUSTRIAL-GRADE DURABILITY:Built with a zinc alloy chuck, solid brass core, and chrome-plated steel body to resist rust, shocks, and corrosion. PVC grip enhances comfort, while the hanging ring offers easy storage in garages or truck cabs. 4.EASY TO USE:Simply press the chuck onto the valve stem to get instant pressure readings. After check pressure, always re-tighten valve caps for a secure seal. 5.UNIVERSAL COMPATIBILITY: The compatibility of the Schrader valve enables it to maintain the optimal tire pressure in trucks, cars, recreational vehicles, SUVs, all-terrain vehicles, bicycles and motorcycles The ATsafepro Dual Head Tire Pressure Gauge is engineered to meet the demands of truckers, RV travelers, and everyday drivers alike. With a focus on durability, accuracy, and ease of use, this gauge solves the unique challenges of dual-wheel setups and hard-to-reach valves while delivering reliable performance across all vehicle types. Dual Head + Extended Reach: Solve Dual-Tire Challenges Designed for dually tires on semi trucks, 18-wheelers, and RVs, the dual chuck system eliminates the need to switch tools: Straight foot chuck: Ideal for inner wheels or deeply recessed valves on commercial trucks and RVs. 30° reverse chuck: Perfect for outer wheels on dual setups, ensuring quick access without awkward angles. The 12.7-inch shaft extends reach to valves on tall vehicles, saving time and effort during routine checks – a game-changer for professional truckers and fleet managers. Accuracy That Counts With a 10-150 PSI/1-10 Bar dual scale and 2 PSI increments, this gauge delivers precise readings for all Schrader valve-equipped vehicles – from cars and SUVs to motorcycles and ATVs. The analog mechanism requires no batteries, making it reliable in extreme temperatures and harsh conditions (e.g., construction sites, cross-country trips). Heavy Duty Build for Lifelong Use Crafted from zinc alloy (chuck), solid brass (core), and chrome-plated steel (body), this gauge withstands impacts, rust, and daily wear – a staple in trucker tool kits and garages. The PVC non-slip handle ensures a secure grip, while the hanging ring allows effortless storage in truck cabs or workshop walls.
