Lightweight but robust, the Fibrelyte Tier 8 enclosure is designed to provide utility access in turf, walkway and other light-duty pedestrian applications, while also providing protection against incidental traffic from commercial landscape equipment and light trucks. Built from a strong yet light polyester, fiberglass, and calcium carbonite composite material, Fibrelyte offers weight comparable to plastic but delivers a greater strength-to-weight ratio than equivalent plastics that meet Tier 8 load ratings. Fibrelyte is quick, simple and safe to deliver, handle and install, while also enabling on-site modifications to be carried out quickly with no need for specialist tools.
