Proven Value and Performance – That’s why they’re Law Enforcement’s #1 Choice. Regardless of how you measure your push bumper’s performance, Setina’s models are in a class by themselves. Along with a touch of the right aesthetics, Setina push bumpers are built for Maximum Performance… and just about everything else. The PB450L is a long ways from our first bumper in the 1970’s, but innovation will always define Setina’s Push Bumper series, establishing them as the most respected and versatile bumpers in law enforcement technology. Often imitated, never outperformed.
