Display warning signs and important information by using document holders that attach to shelves, racking and other metal surfaces in a workshop, warehouse or other workspace. The transparent plastic pocket holds A5 documents and has a magnetic backing so that it can be easily mounted on suitable surfaces. Documents are secure but slide out on either side for easy removal. The document holder is ideal for signs or notices in most settings and can be used to improve workplace safety. They are supplied in a pack of 10 and are available either portrait or landscape.
