Secure your tub with the NotJust4X4 Manual Roller Shutter — engineered specifically for the GWM Cannon. Built to outlast. Priced to be fair.
One promise: the best quality, at the best price. No inflated mark-ups, no gimmicks — just honest, direct pricing on a hard aluminium roller cover that protects your load and lasts the distance. Every kit is a Vehicle-Specific Custom Fit, not a generic universal part, so it mounts flush and looks factory from day one.
Why GWM Cannon Owners Choose This Manual Roller Shutter
1. Best Quality, at the Best Price
You pay for what's in the metal, not for a logo. Powder-coated aluminium slats, fitted precisely to your tub — without the premium-brand markup.
2. Simple, Reliable, Zero Electronics
Open and close it by hand, then lock it with a key. No motors, no wiring, no battery drain — nothing electronic to fail out on the tracks. Two keys are included, and the multi-position lock secures the cover fully closed, half open, or one-third open, so you can lock the tub even while carrying taller gear.
3. Tough Aluminium, Built for the Bush
Powder-coated aluminium slats shrug off sun, rain, dust and corrugations, and the coating resists scratches and fading — so your tub stays protected and your ute keeps looking sharp for years.
4. Vehicle-Specific Custom Fit
Designed around your specific tub and rail profile — not a universal part. Designed around the GWM Cannon's approximately 1562mm-wide tub for a clean, gap-free seal. The result is a clean, gap-free fit that looks factory-installed.
