Features
What is it?
The AC-1 is a one-piece, high-tensile aluminum wheel chock designed to prevent vehicle movement during emergency operations or maintenance. It meets NFPA 1901 requirements and is third-party tested for safety compliance, making it a trusted solution for fire departments and fleet operators.
How is it used?
Place the AC-1 chock firmly against the tire of a parked vehicle to prevent rolling. Its double row of rugged teeth grips firm surfaces like concrete or asphalt. The large rear-opening hand grip allows for easy transport and precise placement. When not in use, it can be stored below the apparatus using compatible holders (sold separately).

NFPA Compliance Note
NFPA 1901 requires that each fire apparatus be equipped with two easily accessible wheel chocks before it can be placed into service. These chocks must be capable of holding a fully-loaded apparatus on a 20% grade hard surface with the transmission in neutral and the parking brake released.
Safety Warning
⚠️ WARNING: Always outfit each apparatus with appropriately-sized chocks for its tires. Undersized chocks may fail to restrain a vehicle, potentially resulting in property damage or injury. Ensure proper sizing and placement for safe operation.
