The IP67 certificate stands for “Ingress Protection” and denotes the trolley’s degree of protection against the ingress of dust and water. The first digit “6” stands for the maximum protection against dust, which makes the trolley dustproof. The second digit “7” stands for protection against temporary immersion in water up to a depth of 1 meter. With this certificate you can be sure that the trolley is robust enough to keep out dust and water and thus protect the contents.
