You wont find a nicer permit panel on the market today. This hinged panel will not cracking and break from buffeting like solid mount versions will. Made from one continuous piece of 18 gauge, hi-polished 18-8 stainless steel. The hinge is formed out of the panel piece, eliminating the potential for rusty bolts, and includes a stainless thru rod. Panel easily mounts to the underside of your cab, and comes with assembled hinge and pre-drilled mounting holes. 5" high x 36" wide.
