Hard One-Piece Tonneau Covers at Trademasters
One-piece covers are exactly what they sound like — a single rigid lid that covers the entire bed. They’re built from ABS plastic or fiberglass with gas-charged struts at the tailgate end, so the whole cover hinges up like a clamshell. When closed, they’re the most secure and weather-tight style of tonneau cover available.
The UnderCover LUX is the premium option in this category. It can be painted to match your truck’s factory colour for a seamless, factory-installed look. The UnderCover SE is the entry-level version — same rugged construction in a raw textured black finish.
Who Should Get a One-Piece Cover?
Truck owners who want a “trunk”: If you don’t regularly haul oversized or tall cargo, a one-piece cover transforms your bed into the most secure, weatherproof storage space you can get.
Guys who want a factory look: Paint-matched one-piece covers like the UnderCover LUX blend seamlessly with your truck’s body. From 10 feet away, it looks like the truck came from the factory that way.
Frequently Asked Questions
Can I haul tall items with a one-piece cover? You’ll need to remove the cover for anything that doesn’t fit under it. Most one-piece covers are designed to be taken off by one or two people when needed, but they’re not as flexible as folding or rolling covers for frequent tall-load hauling.
Are paint-matched covers available for my truck? The UnderCover LUX is available in most factory colours for popular truck models. Let us know your truck and colour code and we’ll confirm availability.
How heavy is a one-piece cover? Most weigh between 50–70 lbs. They’re manageable for removal but definitely easier with two people.
