56" by 56" OD Concrete Pull Box - Heavy Traffic Rated

The inside dimensions of this box are 48" x 48".   Concast's line of customizable concrete pull boxes are designed to interface with Concast's Trench System by creating extra cable training room next to control buildings. Additionally, they can stand alone to be used as a junction box for pulling cables. Standard boxes have floor drains, but they can be ordered solid bottom or completely open. 

Boxes with bolt-down covers are provided with hex head bolts - see drawings for details. For added security, SureLock or Penta Head bolts are available.  Cover ID plates available upon request.
