Worksport’s Panel Design
The single formed aluminum panel is more than 3X thicker*

The panels are made from a single sheet of aluminum and reinforced with a crossbar for exceptional durability and structural integrity.

The edge-to-edge seal prevents water intrusion into the panel, while the seamless single-formed panel eliminates any gap or entry points.

*The aluminum panel is more than 3× thicker than the typical competitor’s panel and up to 4× thicker than what has been used or could be used. Thickness comparisons are based on common materials used in similar applications and may vary by manufacturer.

Flip-up
The Ultimate low-profile hard cover, designed to flip-up for on-the-go full bed access.

Keep Water Out
Specially formulated EPDM seals, paired with closed cell foam corner caps and gap seals create a superior seal that stops water instead of diverting it.

WORKSPORT TONNEAU COVER CARE AND MAINTENANCE
Worksport Hard Truck Bed Covers
Worksport hard tonneau covers are made from rugged durable material and require simple, minimal care.
Cleaning Your Worksport Hard Aluminum Tonneau Cover

To maintain a painted aluminum surface, it's essential to regularly clean and apply a suitable protectant to preserve its appearance and durability. Begin by gently removing any loose dirt to avoid scratching. Rinse the surface with water and apply a gentle, automotive-grade cleaner or a mild dish soap solution to remove grime without damaging the paint. After thoroughly rinsing and drying with a microfiber towel, protect the aluminum with a quality protectant designed for painted surfaces. Products like 303 Aerospace Protectant or a similar high-quality UV protectant are ideal for shielding the paint from the sun's harmful rays and environmental pollutants, while also enhancing the surface's appearance. Regularly inspect for any signs of wear or damage, and reapply the protectant as needed to keep the surface in prime condition. This routine care helps extend the lifespan of painted aluminum surfaces and keeps them looking new. For the best results, always follow the product manufacturer's recommendations for application and maintenance.

Worksport Soft Truck Bed Covers
Worksport soft tonneau covers utilize UV-coated vinyl tarps and require particular attention to maintain their excellent appearance and durability.
Cleaning Your Worksport Soft Vinyl Tonneau Cover

To properly clean and protect a Worksport vinyl tonneau cover, it's important to choose a cleaner that is specifically designed for vinyl surfaces. Start by rinsing the cover with water to remove loose dirt. Apply a vinyl tonneau cover cleaner directly to the surface, allowing it to penetrate for a few minutes before wiping it clean with a soft, lint-free microfiber towel. After cleaning, rinsing off any residue, and allowing the cover to air dry, you might consider applying a vinyl protectant such as B.E.S.T. 30032 SPF 2000 Super Protectant Sprayer for additional UV and stain protection. This routine should ideally be performed every 2-3 months to maintain the cover's appearance and integrity.

It's advised against using household cleaner, dish soap, car wash soap, rubbing alcohol, Clorox or Lysol wipes, and Armor All on vinyl tonneau covers. These products can be too harsh, potentially causing discoloration, drying out the vinyl, or leaving behind a residue that attracts more dirt. Instead, stick with products specifically formulated for tonneau covers, which clean while also conditioning and protecting the vinyl surface.

For black vinyl tonneau covers, a toner can be used in addition to regular cleaners to restore the deep black color. However, frequent use of harsh cleaners or protectants not designed for vinyl can lead to damage over time.

General Tonneau Cover Maintenance

Make sure your Tonneau Cover is Properly Secured to your Truck

You should regularly inspect you tonneau cover to ensure it is properly secured to your truck bed to guarantee its stability. Examine the clamps and/or front mounting bolts for correct installation and confirm they remain tight and correctly aligned. Frequent use, especially on uneven terrains, can lead to vibrations and impacts that may necessitate readjustments to the cover.

Maintain and Regularly Inspect your Latches

You should make it a habit to routinely check and maintain the latches on your tonneau cover. Clear out any accumulated dirt or debris and apply a silicone-based lubricant to ensure smooth operation. Verify that the latches are operating smoothly and engaging with the side rail effectively, which is essential for peak performance and security. During this process, be cautious to avoid applying too much spray on the cover itself and clean off any surplus lubricant from the area around the latches.
