LEER DCC Commercial Truck Cap – Heavy-Duty Work Cap
The LEER DCC commercial truck cap is engineered for fleets, contractors, and tradespeople who demand secure, weatherproof cargo protection on every job. We built the DCC with all-aluminum construction and reinforced framing to handle the daily wear of commercial use—tools, equipment, and materials stay dry and locked up through rain, snow, and dust.
This cap features full side windows for visibility and ventilation, a rear barn-door configuration for easy loading, and heavy-duty three-point locking to keep your gear secure overnight. The DCC mounts flush to your truck bed, maintaining a low-profile work silhouette while maximizing interior cargo volume for ladder racks, toolboxes, and bulk materials.
Built for the job
Aluminum Construction & Reinforced Frame
We manufacture the LEER DCC with marine-grade aluminum panels and heavy-duty extrusions that resist rust, dents, and UV degradation. The frame uses reinforced corner braces and structural ribs to distribute load evenly across the cap, so it won’t flex or crack when you’re hauling ladders, pipe, or stacked material bins.
Every weld point and fastener mount is sealed against moisture intrusion. The same engineering philosophy behind their commercial caps ensures each DCC unit meets fleet longevity standards, often outlasting the truck itself in high-mileage service environments.
Locking & Security Features
Three-Point Locking System
The barn-door rear gate locks at three points—top, bottom, and center—creating a continuous seal that prevents pry attacks and keeps your tools secure on the jobsite overnight. Each lock cylinder is keyed alike to your truck’s ignition for one-key convenience across the fleet.
Lockable Side Windows
Both sliding side windows lock independently with internal latches, giving you controlled ventilation without compromising security. Screens keep insects out during ventilation mode, and the tempered glass resists impact from road debris and jobsite hazards.
Barn-Door Access & Loading Ergonomics
The DCC’s barn-door configuration opens wide to the truck bed sides, eliminating the overhead clearance restrictions of lift gates. You can slide long materials—lumber, conduit, pipe—straight into the bed without tilting or awkward angles.
Doors swing on heavy-duty hinges rated for thousands of open-close cycles, and gas struts hold each door open at 90 degrees so both hands stay free for loading. The wide opening accommodates forklifts and pallet jacks at warehouse loading docks, making the DCC a practical choice for distribution fleets and supply-run vehicles.

LEER DCC commercial cap questions
The DCC fits most full-size pickups including Ford F-150/F-250/F-350, Chevy Silverado, GMC Sierra, Ram 1500/2500/3500, and Toyota Tundra. You'll need to confirm your truck's year, make, model, bed length, and cab configuration when ordering.
LEER manufactures model-specific caps to match OEM bed rail dimensions and stake pocket spacing. Contact an authorized LEER dealer with your VIN or truck specifications to verify exact fitment before purchase.
Yes, the DCC is compatible with most aftermarket ladder racks that mount to the truck bed rails or cab. The cap's flush-mount design and reinforced roof panel support rack systems without interfering with door operation.
Some contractors prefer under-cap racks that mount inside the bed, while others use over-cap systems. Consult your ladder rack manufacturer's compatibility chart to confirm mounting points align with the DCC's profile and your truck bed configuration.
Clean the bulb seals and door gaskets every three months with mild soap and water to remove dirt, road grime, and debris that can compress the rubber. After cleaning, apply a silicone-based seal conditioner to keep the rubber supple and prevent cracking.
Inspect the adhesive foam strips around the door frames annually, and replace any sections that show peeling or compression. LEER dealers stock replacement seal kits, and most seal repairs take less than an hour with basic hand tools.
The DCC is available in fleet white as standard, and LEER offers factory paint-matching for most OEM truck colors at the time of order. Factory-painted caps receive automotive-grade basecoat and clearcoat with UV inhibitors for long-term color retention.
If you need a custom color or want to add vinyl graphics for branding, the aluminum surface accepts paint and adhesive vinyl after light sanding and primer application. Many fleet managers order white caps and apply vinyl wraps for flexibility across multi-brand truck inventories.
The DCC uses all-aluminum construction with barn doors for maximum durability and wide rear access, making it ideal for heavy commercial use and frequent loading cycles. The 100R features a smooth fiberglass shell with a lift-up rear window, offering a more traditional cap profile with lighter weight.
Both caps deliver weatherproof protection and lockable security, but the DCC's reinforced frame and aluminum body hold up better in high-mileage fleet service, while the 100R suits contractors who prioritize sleek appearance and don't require daily forklift loading access.
Yes, the DCC's interior roof panel accommodates LED strip lights, dome lights, and other 12-volt accessories. Most installers tap into the truck's cargo light circuit or run a dedicated wire from the battery through the bed rail conduit.
The cap's aluminum frame provides grounding points for electrical mounts, and you can drill small access holes for wire routing without compromising structural integrity. Many fleet operators install motion-activated LED bars for hands-free illumination when loading tools at night.
With routine seal maintenance and occasional hinge lubrication, DCC caps regularly serve 10 to 15 years in daily commercial use. The aluminum construction resists corrosion in road-salt environments, and the reinforced frame holds up through hundreds of thousands of miles.
Many fleet managers report transferring DCC caps to replacement trucks when the original vehicle is retired, extending the cap's service life beyond a single truck's lifespan. Factory paint finishes typically require touch-up after 7 to 10 years depending on UV exposure and washing frequency.
