AceO’Spades can be attached to roof racks in order to securely transport long-format outdoor equipment such as shovels, paddles or oars. The fasteners are similar to handcuffs and close tightly around bars with a diameter of 30 to 55 mm to hold them tight. Transverse rubber ribs ensure that nothing is damaged or can slide away. Moreover, AceO’Spades can be secured with safety locks to make the transported goods thief-proof.
