ACCESS® LoMax Folding Hard Cover B4040029


    Release both locks simultaneously by pulling the synthetic cord from either side. Heavy duty nylon latches provide 1/2 in. surface for solid positive engagement.
    Unfolding each panel locks the cover automatically at ten points with heavy duty reinforced nylon components.
    Water-shedding design and waterproof hinges route water away from the truck bed, no drains or gutters needed. The hard folding tonneau cover overlaps the bed rails with a continuous seal along the full length of the side rails, preventing rain, dirt, dust and snow from entering the truck box.
    Extruded aluminum channels reinforce the panels to support up to 400 pounds of evenly distributed weight, while weighing approximately 50 pounds for an impressive strength-to-weight ratio.
    Retractable storage clips hold tonneau cover firmly in place and rigid standoffs with vinyl caps keep panels perfectly spaced in the folded position. No adjustments necessary.
    Installs in minutes without the need to drill into your truck box. Specifically cut 'teeth' maintain superior grip and exceptional strength.

With extruded aluminum channels providing additional support, this hard tonneau cover remains rigid and strong enough to handle up to 400 lbs of weight.

Lowest Price Guarantee

We work hard to ensure that the prices of our aftermarket truck bumpers are the best available online. That’s why we guarantee that you’ll get the lowest price on all of our bumpers and accessories. Here’s how it works:

  • We guarantee that the price of our aftermarket truck bumpers is the best available online. If you find an online store that offers a specific model at a lower price, let us know and we’ll match their price for your purchase.
  • If you find that the exact bumper at an even lower price online within 6 months after your purchase, we will refund you the difference. Simply send a price difference refund request to This applies even to the prices from our own store at
  • The competitor must be an online retailer with no physical stores and they must be an authorized dealer of the bumpers or accessories in question. The competing online store must also have the product in stock on their website for our price match guarantee to apply.
  • The price match guarantee does not apply to online marketplaces such as Amazon, eBay, Overstock or any other similar websites. The competitor must be selling the item directly on their own online store.
