FIBERGLASS POLYMER CONCRETE - Pull Box, Junction Box, Hand Hole, Splice Box

Polymer Concrete and Fiberglass Polymer Concrete Pull Box

HIGHLINE PRODUCTS underground pull boxes (underground enclosures) are designed for use in pulling, splicing, and storing cable, as well as for access to underground electric utilities, telephone power, communications, CATV, or water lines. They are an alternative to traditional concrete service boxes. Such products have been proven for over 30 years.

HIGHLINE PRODUCTS concrete-alternative underground enclosures/ pull boxes come in two styles:

1. Hybrid &endash; CHA and CVA Series (large vaults): polymer concrete cover and supporting ring for incidental traffic bearing molded to a fiberglass body for reduced weight.
2. All polymer concrete (PHA and PTA Series).

Traditional concrete and polymer concrete both consist basically of sand, aggregate, and a bonding material. In traditional concrete, the bonding material is Portland cement and water; in polymer concrete, it is resin. Polymer Concrete combines polyester resin with aggregate and is reinforced with fiberglass for exceptional strength and durability. These products are ideal for incidental traffic applications for telecommunications, CATV, DOT, water, utilities and commercial and industrial projects.

CHA/CHG Series

Fiberglass/Polymer Concrete Splice Box, Pull Box

  • Lightweight- box is made of high quality fiberglass, ring and cover are polymer concrete
  • Designed for Tier 8 (12,000lbs), Tier 15 (22,500lbs) applications
  • Flared design provides added work space for easier conduit management compared to compare to all polymer box
  • Cost effective as customer can typically down-grade a box size thus saving money and still provide more working area than a larger sized all polymer box. For example a CHA173024 provides 20% greater working volume compared to a PHA243624 and provides a cost savings.
