The Worksport AL3 (or AL3 Pro) is a low-profile hard folding (tri-fold) tonneau cover made primarily of formed aluminum panels. Its design aims to provide many of the protective, secure, and weather-resistant advantages of a rigid shell, while retaining flexibility to fold (i.e. partially open) the cover for access to cargo without full removal. The panels are formed from aluminum (a single formed sheet, rather than composite sandwich panels) and reinforced with a cross bar for structural strength. It includes “Quick Latch” cable-activated latch mechanisms for opening, and triple-fin EPDM seals to reduce water intrusion. The AL3 is built without requiring cutting, trimming, or drilling in most truck models; it uses clamps and brackets. The finish is a “DiamondSHIELD” ceramic / scratch-resistant coating (a proprietary finish) to help resist abrasions, dents, and weather damage.
Key Features
Here are the standout features of the Worksport AL3:
| Feature | Description / Value |
|---|
| Low-profile design | The cover sits relatively flush (low height) above the bed rails for a sleeker look. |
| Aluminum construction | Ultra-thick, formed aluminum panels (single sheet) with crossbar support for rigidity and durability. |
| Quick Latch system | Cable-operated latches that allow easier opening/closing of the cover. |
| Triple-fin EPDM seals | Seals around edges use multiple fins to help keep out water, dust, and prevent intrusion into the bed. |
| Easy installation (no drilling in many cases) | Worksport advertises “no cutting, trimming, or drilling required” for many truck fits, using clamps & brackets. |
| Fold / partial access | The tri-fold design allows folding back panels (often ~2/3 of bed access) to reach cargo without full removal. |
| DiamondSHIELD / protective finish | A ceramic / scratch-resistant coating to help protect from abrasions, UV, and weather. |
| Weight & rigidity balance | Engineered to be lightweight enough for ease of handling, while still structurally durable. |
| Lifetime support | Worksport advertises “lifetime support” for its tonneau covers, meaning they provide customer support for the product’s lifespan. |
| “Made in the USA” | The product is manufactured in the U.S. (upstate New York) with many domestically sourced components. |
One caveat: although marketed as folding, many users note that it does not fold entirely vertical to lie flat against the rear cab window; it folds partially to access ~2/3 of the bed, but does not provide full vertical bed clearance.
Ideal Use / Applications
The AL3 is best suited for users who want:
A durable and weather-resistant cover that improves over soft roll-up covers.
Quick access to cargo without needing to fully remove the cover.
A sleek, low-profile aesthetic rather than a tall shell.
Moderate security (locks) and protection from elements (rain, snow, dust).
Frequent use of the bed for tools, gear, or general cargo where it's helpful to fold part of the cover.
A cover that balances strength and weight, so that installation and removal are manageable.
Installation Notes & Tips
Here are what I found as best practices and things to watch out for when installing the AL3:
Follow Worksport’s Installation Guide / Videos
They provide model-specific install guides (by make/model/year) and videos.
No Drilling / Cutting for Most Models
The AL3 is designed to install via clamps / brackets without requiring drilling or cutting in many standard truck beds.
Use Provided Hardware
All necessary brackets, clamps, and hardware are included. Do not substitute unless recommended by Worksport.
Alignment & Leveling
Ensure the cover is centered, level, and parallel to the bed rails. Misalignment can cause binding, leakage, or premature wear on seals
Care & Maintenance
To maintain the Worksport AL3 and prolong its lifespan, consider the following tips:
Regular Cleaning
Clean the aluminum panels and finish with mild soap and water. Avoid harsh detergents or abrasive cleansers.
Protect the Finish
Worksport suggests applying a suitable protectant on the painted aluminum surface to preserve its appearance and protect from UV, corrosion, and environmental deterioration.
Seal & Gasket Inspection
Periodically inspect the EPDM seals and corner foam/gasket parts for wear, deformation, or detachment. Replace damaged seals to maintain weather tightness.
Lubricate Moving Parts
Hinges and latches (especially the quick-latch mechanisms) should be cleaned and lightly lubricated (non-petroleum lubricant recommended) to keep them operating smoothly.
Remove Debris / Snow / Ice
Before driving, clear off heavy snow, ice, leaves, or debris from the surface. While the panels are robust, excessive load or sharp debris could harm seals or components.
Avoid Harsh Spray at Seams
When pressure washing or using a hose, avoid directing high-pressure spray into seams, joints, or under the edges of seals which may force water under them.
Warranty & Support
Here’s what I found about the warranty and support for the Worksport AL3:
Warranty Period: 3 years limited warranty on aluminum framing, plastics, and hardware (against defects in material and workmanship).
Scope / Coverage: Covers manufacturing defects in materials or workmanship (for the specified components).
Option for Repair or Replacement: At Worksport’s discretion, they may repair defective parts or replace the product (or components) if repair is not feasible.
Support / “Lifetime Support”: While the warranty is 3 years, Worksport advertises “lifetime support” meaning they will provide assistance and parts / support for the life of the cover (beyond strict warranty).
Exclusions: Damage caused by misuse, abuse, improper installation, accidents, modifications, or normal wear & tear likely will not be covered.
Claim Process: Typically, you’ll need to provide proof of purchase, serial / lot number, photos, and submit a warranty claim. The manufacturer may require Return Authorization for parts returns.
