Vista System directories are fast, easy and simple to assemble and install. No need for special tools. They accept numerous insert materials and are low in cost. The system has the advantage of flexibility to accept a variety of insert materials as well as the complete freedom to determine the height of each information strip - You decide how the sign will be sectioned by placing the separation strips as needed. The separation strips come with double-sided adhesive on the back, just peel and attach. Where? Wherever you decide, according to your design.
