Freightliner FLC112 Deck Plates & Air Line Boxes

Frequently Asked Questions About Freightliner FLC112 Deck Plates & Air Line Boxes

What are deck plates and air line boxes used for on the FLC112?

Deck plates provide a durable mounting surface behind the cab where air lines, electrical lines, and gladhands connect to the trailer, while air line boxes house and protect the air and electrical connections in that same area. Together they help organize and shield these critical hookups from road debris, moisture, and general wear.

Will these parts fit my Freightliner FLC112 without modification?

Products listed in this category are designed to match the factory fitment for the FLC112, but slight variations can occur between production years or if your truck has aftermarket modifications. We recommend comparing measurements and mounting hole patterns to your existing deck plate or air line box before ordering to confirm a proper fit.

What materials are these deck plates and air line boxes made from?

Most deck plates and air line boxes are constructed from steel or aluminum for durability and corrosion resistance. Steel components typically offer added strength, while aluminum options provide a lighter weight alternative with good resistance to rust. Check the specific product listing for the exact material used.

Do these parts come pre-drilled or finished, or will I need to do additional prep work?

Many deck plates and air line boxes come pre-drilled to match factory mounting patterns, but this can vary by manufacturer and part number. Some parts may be sold in raw or primed finish and require painting to match your truck, while others may come with a finished coating. Always check the product description for finish and drilling details before purchase.

How difficult is it to install a replacement deck plate or air line box?

Installation difficulty depends on the specific part and the condition of your truck's existing mounting points. In general, replacing a deck plate or air line box involves removing the old unit, transferring or reconnecting air lines and electrical connections, and securing the new part in place with bolts or fasteners. Having basic hand tools and a service manual on hand can make the process smoother, and a qualified technician can help if you are unfamiliar with air line and electrical routing.
