Lightweight aluminium construction, collapsible, and with a modular design that allows the easy replacement of damaged parts. A long lifetime is thereby guaranteed. The collapsible boxes are made from hard-wearing tarpaulin, and when folded up they require very little storage space. Straps can be fixed at the side to ensure optimal protection against the elements. Suitable for the Post Caddy and almost all standard mail trolleys. The All-in-One version with extra-strong base is suitable for bicycle delivery.
