Why CMX?
Built Around the Truck Features That Matter
CMX is Cap-it's value-focused aluminum canopy. It delivers the utility truck owners actually use without forcing every customer into the highest-priced end of the canopy market.
Real Aluminum Construction
Aluminum alloy panels and structural components deliver practical strength while helping resist corrosion from weather, road salt and outdoor exposure.
Access From Either Side
Large lift-up gullwing doors let you reach equipment directly from either side instead of climbing through the rear opening.
Light + Ventilation
Sliding glass windows brighten the enclosed bed, improve visibility and provide adjustable airflow.
Serious Roof Capacity
A 200 kg dynamic and 300 kg static canopy roof rating creates a strong foundation for compatible racks, cargo systems and rooftop equipment.
Vehicle-Specific Fitment
CMX applications are designed around supported truck generations and bed lengths for a cleaner fit than a generic universal canopy.

Modular by design
Best-Value Aluminum Does Not Mean Bare-Bones
CMX arrives as a modular canopy system rather than a fully assembled factory-built cap. Combine that efficient design with Cap-it buying power, Canadian distribution and an established retail network, and the result is a canopy priced very differently from much of the traditional aluminum-canopy category.
The value is not an apology for the CMX. It is the reason CMX exists.
Built for everyday use
Gullwing Doors With Sliding Side Windows
The Side Windows CMX combines fast side access with the light, visibility and ventilation many customers prefer in a traditional truck canopy.
Large lift-up gullwing doors on both sides let you walk up to the truck and reach cargo immediately. Integrated sliding glass windows brighten the enclosed bed and allow adjustable airflow without opening the complete side door.
For pet owners, the sliding windows provide added light, visibility and ventilation for appropriately secured transport. Owners remain responsible for proper restraint, supervision and safe temperature management.
- Lift-up gullwing access on both sides
- Sliding glass window in each side door
- Adjustable airflow when windows are opened
- More natural light inside the canopy
- Improved outward visibility
- Lockable side doors
- Lift-up rear door with glass
- Fixed front glass for rearward visibility

Designed to go together
A Straightforward Modular Assembly Process
Not all modular canopies are engineered equally. CMX is designed to assemble cleanly and efficiently, with a straightforward process and a complete step-by-step video available for customers and installers who want to see how it goes together.
Professional assembly and installation through Cap-it are recommended for correct fitment, sealing, wiring, adjustment and water testing.
Watch the CMX Assembly Video →Roof Load and Rack Options
Build up
Serious Roof-Load Capability
The CMX is designed to support compatible roof racks, cargo systems and rooftop equipment when correctly assembled and installed.
The canopy structure is rated to a 300 kg (661 lb) static roof load and a 200 kg (440 lb) dynamic road load.
Optional CMX Roof Rack Systems are available in low-profile and high-profile configurations.
Low-Profile Rack
Keeps cargo closer to the canopy and helps minimize overall vehicle height.
High-Profile Rack
Adds clearance for bulkier loads and compatible rooftop-tent installations.
The vehicle, truck bed, mounting system, rack and complete load must remain within all applicable ratings.
Construction and Weather Protection
Built for the truck
Aluminum Strength for Work and Adventure
The CMX uses aluminum alloy panels and structural components to deliver the durability expected from an everyday truck canopy while helping resist corrosion from weather, road salt and outdoor exposure.
- Aluminum alloy panels and structural components
- Multi-stage protective coating
- ASTM B117 salt-spray tested for more than 720 hours
- Vehicle-specific applications
- Lock covers included on all six locks
- Included third brake light
Canadian conditions
Sealed, Installed and Water-Tested
The CMX canopy carries an IP65 water-resistance rating and is designed to resist rain and water spray when correctly assembled, sealed and installed.
During a professional Cap-it installation, the canopy panel joints and connection between the canopy and truck-bed rails are sealed before the completed installation is water-tested.
A conventional pickup bed and tailgate should not be considered completely waterproof or dustproof.

Warranty and Support
Warranty & support
Backed by Cap-it
The Cap-it Bulldog CMX Modular Aluminum Canopy includes a 1-year structural warranty covering the canopy structure and panels, plus a 120-day limited warranty covering wearable components.
Cap-it's Canadian retail and distribution network also provides fitment guidance, installation support, warranty assistance and replacement-parts support.
The Cap-it take
For $200 More, the Windows Make a Lot of Sense
The Side Windows CMX keeps the same aluminum structure, gullwing access and serious roof capability as Side MOLLE, then adds sliding glass windows to both sides.
For customers who use their canopy every day, travel with family, camp regularly, transport pets in an appropriately secured setup or simply prefer more light and visibility, that is a meaningful upgrade for a relatively small difference in price.
If exterior MOLLE is not a priority, this is likely the CMX most customers will want.
