Flip-n-Lock Placards

The Flip-n-Lock system uses a metal placard holder mounted permanently to the vehicle and individual placard legends that snap into place with a firm locking clip, allowing a driver to flip out the current legend and snap in the appropriate replacement placard in seconds with no tools required - a major time saver for carriers transporting multiple hazmat classes across different runs.

Yes, stainless steel clips on our Flip-n-Lock hazmat placards offer significant advantages over aluminum clips by maintaining snapping power and load-bearing strength over time and resisting rust and corrosion, making them ideal for wet conditions, rain, and coastal routes where aluminum clips would corrode and lose their locking effectiveness.

We offer Flip-n-Lock placard legends for all DOT hazmat classes from our complete hazmat placards collection, including flammable, non-flammable gas, poison gas, flammable liquid, flammable solid, oxidizer, poison, radioactive, corrosive, and dangerous, allowing carriers to comply with 49 CFR placard requirements for any hazmat class using a single set of holders mounted to the vehicle.

Yes, our Flip-n-Lock placard holders feature a drainage channel built into the base that allows water to drain away rather than pool behind the placard, a design advantage not commonly found on competing flip placard systems that prevents moisture buildup, corrosion of mounting hardware, and premature deterioration of the placard legend.
