Factory Overview

Frequently Asked Questions (FAQ)

What materials are best for long-term durability in roof boxes?
We recommend a blend of ABS (Acrylonitrile Butadiene Styrene) for impact resistance and an ASA (Acrylonitrile Styrene Acrylate) top layer for superior UV resistance and weatherability. This ensures the box won't become brittle or fade over time.
Do your roof boxes fit all vehicle types?
Our "Universal" series is designed to fit most crossbar systems (square, aero, or wing-shaped). We offer sizes from 320L to 700L to accommodate everything from compact cars to full-size SUVs.
What is your lead time for OEM orders?
For existing molds, our standard lead time is 25-35 days. For custom ODM projects requiring new tooling, the design-to-prototype phase takes approximately 4-6 weeks, with mass production following shortly after.
How do you ensure the safety of the locking systems?
All Macajor roof boxes feature a multi-point centralized locking system. The key can only be removed if all locking points are securely engaged, preventing accidental opening during transit.
