This document provides installation instructions and product information for the TRAILFX GM Underrail Bedliner/Tailgate Cover, identified by part numbers 21020X, 21022X, and 21024X.

Function Description:

The TRAILFX GM Underrail Bedliner/Tailgate Cover is designed to protect the bed and tailgate of a pickup truck. The bedliner provides a durable surface that shields the truck bed from dirt, debris, and potential damage from cargo. The tailgate cover offers similar protection for the tailgate, ensuring its longevity and maintaining its appearance. The underrail design means the bedliner's edges fit beneath the truck's siderails, providing a clean, integrated look and preventing cargo from getting trapped underneath the liner's edges. The product aims to enhance the durability and utility of the truck bed, making it suitable for various hauling tasks while minimizing wear and tear on the original truck surfaces.

Routine Care: Users should sweep out dirt and debris from the bed regularly and pick up items that could scratch the liner.
