Key Features & Benefits

Aluminum Alloy Construction & Finish
Constructed from aluminum alloy panels and structure, the CMX features a durable, multi-stage coated finish designed to resist corrosion, road salt, and everyday wear in Canadian driving conditions.

Gullwing Side Doors with Sliding Glass Windows
The CMX Side Windows canopy features lift-up gullwing side doors on both sides, each equipped with sliding glass windows.

These windows improve outward visibility from the cab, allow natural light into the truck bed, and provide controlled airflow when opened. Sliding windows are especially popular with pet owners, offering ventilation and visual connection when transporting dogs in the truck bed (with appropriate restraints and setups).

Rear Lift-Up Door with Secure Locking
The rear door provides full-height access to your truck bed and features secure locking hardware for everyday security.

Lock Covers Included
Lock covers are included as standard on all six door locks, helping protect lock mechanisms from dirt, moisture, and road debris while maintaining a clean, finished appearance.

Integrated Third Brake Light
The CMX canopy includes a high-mounted third brake light as standard, improving rear visibility and safety once installed.

Roof Load Capability
The CMX is rated to support practical roof-mounted accessories such as racks, cargo carriers, and rooftop gear.

Static roof load: 300 kg (661 lb)
Dynamic road load: 200 kg (440 lb)

These ratings apply to the canopy and compatible roof rack systems.

Weather Protection (Canopy)
The CMX canopy carries an IP65 water resistance rating, meaning it is designed to resist rain and water spray when properly assembled and sealed.

As part of standard installation, the canopy is sealed at all panel joints and sealed to the truck bed rails. Pickup truck beds are not waterproof by design, and water intrusion can still occur through tailgates and factory bed seams.

For customers wanting additional protection, upgraded bed sealing options are available. Ask your local Cap-it store for details, as solutions vary by truck and application.

Clean, Vehicle-Specific Fitment
Designed to suit modern truck beds, the CMX delivers a tidy, well-integrated appearance that complements the lines of your truck.

Optional Roof Rack Systems

The Bulldog CMX Modular Aluminum Canopy is compatible with optional Cap-it roof rack systems, all rated to match the canopy’s load capacities.

Low-profile roof racks are ideal for ladders, building materials, and everyday cargo while keeping overall vehicle height to a minimum.

High-profile roof racks provide added clearance above the canopy roof, making room for bulkier cargo or accessories such as rooftop tents.

Your local Cap-it store can help configure the right rack setup based on how you use your truck.

Professional Installation by Cap-it

Professional installation at a Cap-it store is recommended to ensure correct assembly, fitment, and long-term performance.

A standard Cap-it CMX installation includes:

Unpacking and responsible disposal of all packaging materials
Full canopy assembly and mounting to the truck bed
Sealing of all canopy joints and sealing to the truck bed rails
Wiring and connection of the included third brake light
Water testing prior to vehicle handover
A walk-around to review features, operation, and care of your new canopy

While the canopy itself is sealed and water-tested, pickup truck beds are not waterproof by design. Water intrusion can still occur through tailgates and factory bed seams.

Optional upgraded bed sealing solutions are available and can further reduce water entry depending on vehicle design and application. Ask your local Cap-it store for details.
