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.

Quazite PG2436BA24 – Frequently Asked Questions

1) What are the dimensions of the Quazite PG2436BA24 underground box?
The PG2436BA24 is a 36-inch x 24-inch x 24-inch straight-wall enclosure. The straight (non-tapered) wall profile means the interior footprint stays the same from the top of the box to the bottom, so you get the full working area at the splice depth rather than a pinched bottom. Plan your excavation for the outside footprint plus room to work and backfill around the walls.
2) Does the PG2436BA24 come with a cover?
The PG2436BA24 is the box only, a precast fiberglass reinforced polymer concrete enclosure with a standard open bottom. The cover is a separate item and has to be ordered to match the 36 x 24 opening and the load rating your application calls for (pedestrian walkway versus incidental or deliberate vehicular traffic). Specify the cover with the legend you need, such as ELECTRIC or COMMUNICATIONS, at the same time so the box and lid arrive as a set.
3) What does open bottom mean on an underground pull box, and do I need to pour a floor?
Open bottom means the box has four walls and no cast floor, so it sets directly on prepared bedding instead of a slab. Standard practice is to set it over compacted crushed stone or gravel, which lets water drain out through the bottom instead of standing in the box and lets conduit and cable enter from below the walls. No pour is required. If you are in soil that does not percolate or in a high water table, you still need a drainage plan, because an open bottom only drains as well as the ground under it.
4) Should I use an open bottom box or a closed bottom box for an underground splice vault?
Open bottom, like the PG2436BA24, is the usual choice for electrical and communications pull and splice boxes where you want water to drain away and conduit to come up from below. Closed bottom is what you want when the box has to hold something that cannot sit over open soil, when you are setting in standing water or contaminated ground, or when the enclosure is used as a sump or meter pit. For a straightforward cable junction or service access point over free-draining stone, open bottom is the simpler install.
5) Is polymer concrete better than traditional precast concrete for a direct burial box?
The difference is weight and corrosion behavior. Quazite's fiberglass reinforced polymer concrete is lighter than conventional reinforced concrete of the same size, which matters when you are placing a 36 x 24 x 24 box without a boom truck, and it resists the corrosion, cracking and moisture intrusion that break down ordinary concrete enclosures below grade. Conventional concrete is heavier for the same box and generally needs equipment to set.
6) Can the Quazite PG2436BA24 be used for fiber and telecom, or is it electrical only?
It works for both. The PG2436BA24 is used for underground electrical cable splicing and junctions, telecommunications and data infrastructure vaults, utility distribution and service access points, and conduit runs in new construction or retrofit. The box itself is non-conductive polymer concrete, so the application is set by the cover legend you pair with it, not by the box.
7) Can I stack Quazite boxes to get more depth than 24 inches?
Depth on the PG2436BA24 is 24 inches as a single straight-wall unit. Where a deeper vault is needed, the normal approach with straight-wall polymer concrete boxes is to add a matching extension of the same 36 x 24 footprint under the top section rather than trying to bury the box lower and extend the grade ring. Confirm the footprint matches exactly before combining sections, since straight-wall and tapered-wall boxes do not mate.
