Foldable Student Backpack Trolley Frame

Foldable Student Backpack Trolley Frame   This retractable pull rod frame is a core spare accessory for children rolling school backpacks, student trolley bags and lightweight backpack luggage. We adopt high-strength aluminum tube to keep the frame light weight without sacrificing load capacity. The foldable telescopic design makes it easy to store when not in use. The built-in locking structure prevents slipping during pulling. The base bracket fits most common trolley backpacks and can be used as a direct replacement for broken frames. Customization includes adjustable rod length, bracket structure, grip color and brand logo. Every piece passes quality testing before delivery. We offer low MOQ trial orders and large bulk OEM supply for backpack factories, bag brands and hardware distributors globally.
