Fibrelyte® FL8T bolt-down lid provides a lightweight, high-strength access cover designed for FL8 valve boxes used in irrigation and water utility installations. Engineered from Fibrelyte's proprietary composite, the FL8T combines durability with easy handling to simplify installation and service work.

  • Material: Fibrelyte® composite—polyester resin reinforced with fiberglass and calcium carbonate for superior strength-to-weight performance.
  • Compatibility: Fits FL8 valve boxes (nominal 9 x 12 inches) and installs flush with the box when correctly seated.
  • Identification & Security: Factory-stamped "Water" and a bolt-down design secure the lid to the box to prevent accidental displacement.
  • Duty Rating: Rated for light-to-medium (Tier 8) non-deliberate traffic—suitable for pedestrian areas and incidental landscape equipment traffic.
  • Benefits: Much lighter than concrete lids for faster, safer handling, reduced shipping costs, and easier on-site modification with common tools.

The FL8T is an ideal choice when you need a durable, low-maintenance cover that reduces labor and transport effort without sacrificing protection.
