Quazite Precast Polymer Concrete Fiberglass-Reinforced Underground Box

Quazite Precast Polymer Concrete Fiberglass-Reinforced Underground Box

The Quazite precast underground box family is built for straight-run electrical, telecommunications, and utility applications, available in box dimensions ranging from 24-Inch x 13-Inch x 18-Inch to 30-Inch x 17-Inch x 18-Inch. Every box in this family features a standard open bottom configuration, allowing it to sit directly over compacted earth, gravel, or drainage fill at the installation site. Constructed from polymer concrete reinforced with fiberglass, these boxes combine the structural strength of traditional concrete enclosures with the corrosion resistance and reduced weight of composite materials, making them a durable choice for below-grade cable, splice, and equipment access points. Whether you select the smaller 24-Inch x 13-Inch x 18-Inch footprint or the larger 30-Inch x 17-Inch x 18-Inch option, the same rugged construction and straight, open-bottom configuration carry through the entire lineup.

Key Features
