Compatibility: Ensure accessory dimensions match the tray width, height, and type (ladder, ventilated, solid-bottom).

Installation: Some accessories require specific fasteners or mounting hardware; check manufacturer guidelines. Standards Compliance: Verify CE, UL, NEMA, or ASTM certifications for safety and regulatory compliance.
