Find Stainless Steel Freightliner Classic Catwalks & Airline Boxes

Choose from smooth or diamond tread deck plates crafted from stainless steel or aluminum-both tough enough for the long haul. Aluminum offers a lightweight, paintable surface, while stainless steel delivers a polished, mirror-like finish that resists corrosion. Deck plates come in a range of sizes, typically from 2 to 10 feet, letting you customize your setup for your frame and configuration. The air line box selection offers several styles to fit your preference. Go for a top-mounted design if you want easy access and a bold, elevated look. A recessed or flush-mount style provides a smooth, integrated finish that keeps your hoses protected and out of sight. For open, utility-driven setups, trough-style boxes run the length of your deck plate and make managing trailer hookups simple. Or choose a low-profile coffin-style box for a streamlined, custom touch. Air line boxes can be ordered with blank or pre-drilled designs to fit single or double trailer hookups, giving you the flexibility to match your air and electrical systems exactly how you want them. You can pair your upgrade with related products like: Freightliner Classic frame light bar panels, Freightliner Classic frame-mounted toolboxes, and Freightliner Classic frame steps. Add filler sections or step inserts to complete your layout, improving both traction and overall fitment. With durable construction and a clean finish, these components bring together functionality and style-helping your Freightliner Classic stand out on the road while staying organized and road-ready.
