Fibrelyte FL36BOX12 Composite Meter Box, 17 x 30 x 12 in

Fibrelyte® FL36BOX12 is a lightweight, high-strength composite meter box engineered for underground utility and meter installations. Its proprietary blend of polyester resin, fiberglass and calcium carbonate delivers strength comparable to traditional concrete enclosures while reducing handling and transportation effort.

• Material: Fibrelyte composite (polyester resin, fiberglass, calcium carbonate) for corrosion resistance and long-term durability.
• Dimensions: 18-5/8" W × 31-5/8" L × 12" D (nominal opening 17" × 30").
• Weight: Approximately 40 lb for easier lifting and staging on site.
• Design: Flared side walls and rectangular opening for secure cover seating and easy access to utilities.
• Traffic rating: Rated for medium-duty, non-deliberate traffic—suitable for meter pits and light roadway applications.
• Benefits: Lighter than concrete, simplifies installation, lowers shipping costs, and reduces crew fatigue during handling.

This enclosure works well for municipal and contractor use where durable, corrosion-resistant, and lower-weight options are preferred. For safe installation, set the box on a properly prepared compacted base and follow local codes and utility company specifications.
