# LockNFlate XL Locking Air Chucks for Large Bore Tire Valves (Open Flow & Closed Flow – LNL65021-BSPT & LNL65022-BSPT) - Warranty

## Heavy-duty LockNFlate® XL tire chucks designed for large bore (VG12/12V1) Schrader-type valves on big equipment. These right-angle locking air chucks feature a ~4″ extended nose for deep wheel recesses and six hardened steel jaws that lock onto “big bore” valve stems. Two models are offered – an Open-Flow and a Closed-Flow version – both with 1/4″ BSPT threaded inlets for compatibility with regional air hose standards (functionally identical to the 1/4″ NPT U.S. models). Once clamped on, the chuck creates a secure, leak-free connection and allows hands-free, high-volume tire inflation up to 250 PSI.
