Heavy-duty aluminum ladder rack for flat-roof enclosed cargo trailers. Lightweight extruded aluminum construction with a lifetime rust-free guarantee — won't corrode, won't bend, and won't need repainting every few years like a steel rack will. Available in 5 fixed widths (5 ft, 6 ft, 7 ft, 8.5 ft) plus an adjustable width version that spans 6 ft to 8.5 ft, covering the full range of standard enclosed cargo trailer widths.

Bolt-on installation, mounts to the roof rail of any flat-top enclosed cargo trailer, and carries ladders, conduit bundles, lumber, pipe, kayaks, or anything else you need to keep off the trailer floor and out of the weather.

⚙️ Why Aluminum Over Steel

• Rust-free for life — no paint chips, no rust bleed, no annual refinishing. Critical for trailers that see salt, moisture, or coastal use.
• Roughly half the weight — aluminum is ~3 lb per section vs 10-15 lb for comparable steel. Easier to lift onto the roof, less payload capacity consumed.
• Cleaner appearance — mill aluminum finish looks factory-fresh for years. No flaking or fading.
• Doesn't gall hardware — aluminum is gentler on stainless or zinc-plated bolts than bare steel; easier to disassemble years later.

📏 Choosing the Right Width

• 5 ft — fits standard 6' wide enclosed cargo trailers (the rack mounts inside the rooftop rails, so a 5 ft rack on a 6 ft trailer leaves clearance). Best for small 5x8, 6x10, 6x12 trailers.
• 6 ft — fits 7' wide enclosed trailers (7x14, 7x16, 7x18). The most common trailer size on the road.
• 7 ft — fits 8' wide enclosed trailers (8x16, 8x20, 8x24), including most contractor-grade and car-hauler enclosed trailers.
• 8.5 ft — fits full 8.5' wide enclosed trailers (8.5x20, 8.5x24, 8.5x28), the largest common enclosed cargo trailer size.
• Adjustable (6-8.5 ft) — telescoping / extendable design that fits anywhere from 6 ft to 8.5 ft roof rail spacing. Perfect if you're not sure of exact measurements or you may move the rack between multiple trailers.

Tip: measure from the outside of one rooftop rail to the outside of the other — that's the dimension you're matching. Leave 1–2" of clearance for mounting hardware.

🔧 Installation Notes

1. Confirm your trailer has a flat roof (not a curved or rounded roof). This rack is designed for flat-top enclosed trailers only.
2. Measure the outside-to-outside distance of your roof rails; match that to a width option (add 1–2" clearance for hardware).
3. Position the rack squarely on the roof rails and mark the mounting bolt locations.
4. Drill through the roof rails for through-bolts (3/8" hardware typical; sold separately).
5. Install with oversized fender washers on both sides of the rail to distribute load and prevent pull-through.
6. Seal around each bolt hole with marine-grade sealant to prevent water intrusion into the trailer interior.
7. Torque to snug — aluminum is softer than steel, don't over-crank.

💡 Pro Tips

• Two racks are better than one. For carrying a ladder, you need a front and rear rack — one keeps things from rolling, two keep them from sliding. Consider ordering a matched pair.
• Add tie-down points. The top of the rack accepts aftermarket tie-down eyes; straps secure cargo.
• Adjustable is safest for multi-trailer shops. If you run more than one trailer, the adjustable version fits anything. Fixed widths are simpler and slightly lighter.
• Keep lag bolts out. Never use screws into wooden roof framing — only through-bolt to the aluminum rail. Roof screws will pull out under load.

❓ FAQ

Q: Will this fit my curved-roof trailer?
No. This is designed for flat-roof enclosed cargo trailers only. Curved roofs (common on recreational trailers and some older cargo units) require a different rack design.

Q: How much weight can it carry?
The rack itself is rated for a typical ladder or pipe load (~150 lb across the section). Total capacity is usually limited by your roof rails, not the rack — check your trailer manufacturer's roof load rating before loading heavy cargo.

Q: Is mounting hardware included?
No. Through-bolts, fender washers, and nylock nuts sold separately. Any standard 3/8"–1/2" trailer hardware works.

Q: Can I install one at each end of the trailer?
Yes — this is how most ladder/conduit hauls work. Order two of the same width, install one near the front and one near the rear of the roof.

Q: How do I know what width to order if my trailer is between sizes?
Go with the Adjustable (6-8.5 ft) version. It telescopes to fit anywhere in that range and eliminates the risk of ordering the wrong size.

Q: Will this fit a V-nose trailer?
Yes, as long as the roof is flat (not curved). V-nose only affects the front of the trailer, not the roof profile.
