Fibrelyte®'s exclusive composite formulation combines polyester resin, fiberglass and calcium carbonate to deliver a lightweight yet high-strength valve box lid. Compared with concrete or standard plastic lids, this proprietary material is easier to handle during installation and service, reducing labor and transport costs while providing reliable, long-term performance in outdoor irrigation and utility applications.

  • Material: Polyester resin, fiberglass and calcium carbonate composite for high strength-to-weight ratio.
  • Size: 9" round diameter lid designed for standard 9-inch valve boxes.
  • Installation: Drop-in, flush-fit design that sits level with the box when installed.
  • Identification: Stamped with "Water" for quick identification of irrigation service points.
  • Load Rating: Rated for medium-duty, non-deliberate traffic - suitable for most residential and light commercial landscaping applications.
  • Compatibility: SKU FL8D - intended as a drop-in lid for compatible FL08T valve box bodies.

This Fibrelyte lid is low-maintenance, resists cracking and weathering, and is simple to modify in the field with standard tools if minor adjustments are needed. It is ideal for contractors, landscapers and maintenance crews who need a durable, lightweight cover that installs quickly and reduces handling time. Not intended for deliberate vehicular traffic or heavy industrial use.
