Quazite PG2436BA24 Fiberglass Reinforced Polymer Concrete Underground Box, Open Bottom

Quazite PG2436BA24 Precast Fiberglass Reinforced Polymer Concrete Underground Box

The Quazite PG2436BA24 is a precast, fiberglass reinforced polymer concrete underground enclosure engineered for direct-burial electrical, communications, and utility infrastructure. Measuring 36-Inch x 24-Inch x 24-Inch, this straight-wall box features a standard open bottom configuration, allowing it to be set directly over gravel or native soil for drainage and cable routing access. Built from Quazite's proprietary polymer concrete formulation reinforced with fiberglass, this box delivers the structural integrity required for below-grade installations while resisting the corrosion, cracking, and moisture intrusion that commonly degrade traditional concrete enclosures over time.

Key Features

• Box Dimensions: 36-Inch x 24-Inch x 24-Inch straight-wall enclosure sized for underground cable splicing, junction, and equipment access applications.
• Durable Construction: Precast fiberglass reinforced polymer concrete material provides high strength-to-weight performance and long-term resistance to corrosion, chemical exposure, and ground moisture compared to conventional concrete boxes.
• Standard Open Bottom: Open-bottom configuration allows direct placement over prepared gravel bedding, supporting natural drainage and simplified cable entry from below the enclosure.
• Straight-Wall Design: Uniform vertical wall profile maximizes usable interior workspace for splicing, terminations, and equipment staging within the enclosure footprint.
• Precast Manufacturing: Factory-precast construction ensures consistent wall thickness and dimensional accuracy from unit to unit, simplifying installation planning and cover fit-up in the field.
• Lightweight Handling: Polymer concrete composition is lighter than traditional reinforced concrete of equivalent size, easing transport and placement during underground installation.
