Extang Solid Fold ALX
Hard Tri-Fold Tonneau Cover

The Extang Solid Fold ALX is one of the most award-winning tonneau covers on the market, consistently recognized by truck accessory reviewers for its combination of tough aluminum construction, versatility and ease of installation. The ALX (Aluminum eXtra) designation indicates the upgraded aircraft-grade aluminum used in the panel frames.

Key Features

• Aircraft-grade aluminum panel frames — stronger and lighter than standard steel
• EZ-Lock clamp system — installs without any tools in under 30 minutes
• Compatible with most truck toolboxes — rare for a hard folding cover
• Weathertight seal system with rubber gaskets on all four sides
• Full bed access when all three panels are folded forward
• Prop rod holds cover open for loading tall cargo
• Drain tube system built into the rail

Toolbox Compatibility

One of the standout features of the Solid Fold ALX is its toolbox-compatible rail design. Most hard folding covers cannot be used alongside a crossover toolbox. The Extang solves this by raising the forward rail section to accommodate standard crossover toolboxes — making it one of the few hard covers that truly combines security with contractor-level utility.
