HIGH QUALITY MATERIAL: This firewall pass-through bracket is made of 6061 aluminum alloy and CNC machined, the surface is anodized for corrosion resistance and durability. ANTI-FRICTION: The wire harness holes on the firewall pass-through bracket are curved to minimize the damage caused by friction on the wire harnesses, and will not damage the wire harnesses even after prolonged use. EASY INSTALLATION: This is a two-piece design, the top and bottom halves are bolted together with the center bolt, and then the bracket is secured to the car with the remaining 4 bolts. You can remove the top half of the bracket so there is enough room to install or remove the wiring, then just bolt it together and reinstall the car bracket bolts.
