The Peterbilt 587 2013 And Newer MagLatch Retrac Grille Guard Mounting Brackets are made of carbon steel and feature a zinc-plated finish for lasting rust resistance. Constructed with high-strength steel, these brackets offer maximum rigidity. The folding magnetic latch system allows the grille guard to fold down for easy under-the-hood access. The fold-down latches use 2-3/4 inch rare earth magnets to secure the grille guard upright, and an included safety pin adds extra security. With a vehicle-specific design, these brackets offer a secure, no-drill installation and built-in adjustments for easy installation with variations in frame attachment points. Fits most Peterbilt 587 Series 2013 and newer makes and models.
