DOT Flip Placards Make Using Mandatory Signage Convenient.
As the hazardous content of your container changes, so can your placard. These signs are laid on top of one another with a hinge in the middle, so changing your placard is as simple as turning a page. Placards are constructed of rust-proof aluminum. Stainless steel reinforced clips keep signs securely in place. Placards measure 13 ¾ x 13 ¾.
