Numer-All Aluminum Flip File Placard Set - Durable DOT Hazmat ID

In this review of the Numer-All Aluminum Flip File Placard set, the bottom line is simple: this is a practical, DOT-compliant solution for drivers and safety managers who need to change hazardous materials placards quickly on the road. The reviewer found the flip file system especially useful for fleets that haul varied loads because the set ships with eight commonly required legends in a fade-resistant baked-on polyester finish, and the reinforced quick-release clamps keep panels secure in wind and motion. If you need a durable, reusable placard system that meets 49 CFR 172.519, this set is worth considering.

Key Features

• Fade-resistant finish: The baked-on polyester finish preserves legend legibility over time, reducing replacement frequency for fleets that operate year-round.
• Multiple legends included: The set includes eight screen-printed legends such as Class 3 Flammable Liquid and Division 6.1 Poison/Toxic so users can cover common hazmat needs immediately.
• DOT compliant: Flip placards meet DOT placarding specifications of 49 CFR 172.519, ensuring the system is acceptable for regulatory identification of hazardous loads.
• Secure clamps: Stainless steel reinforced quick-release clamps hold panels firmly in place, providing wind protection and reliable retention during transit.
• Corrosion-resistant back plate: The heavy.032 in aluminum back plate offers wind protection and durability, and contains post-consumer recycled content.

Who It's For

This product is ideal for truck drivers, fleet safety managers, and hazardous materials shippers who need a compact, changeable placard solution that stays compliant with DOT rules. Its preset legends cover many of the most frequently encountered hazard classes, so small fleets or mixed-load haulers will find it immediately useful.

Those who should look elsewhere include operations that require custom or uncommon UN numbers on permanent placards, or users who need fully painted, single-purpose placards instead of a reversible flip system. For static, one-load applications a fixed placard may be simpler.

• Includes eight screen-printed legends to cover common hazardous classes out of the box.
• Reinforced quick-release clamps and a corrosion-resistant back plate deliver secure mounting and wind protection.
