56" by 56" OD Concrete Pull Box

Concast's line of customizable concrete pull boxes are designed to interface with the Concast's Trench System by creating extra cable training room next to control buildings. Or, they can stand alone to be used for pulling cables. Our fully customizable pull box packages include covers and cast-in lifting hardware. Pedestrian covers are available in aluminum. Traffic rated covers are available with a cast iron manhole, or in galvanized steel; either standard or spring assisted. Drain holes in the bottom of the box are standard; please specify when ordering if you want the drain hole removed or if you want a completely bottomless box. Other optional hardware are ladder rungs, our Con-Duct PVC terminations, conduit sleeves/holes, knockouts, pulling eyes, threaded inserts, unistrut, insert plugs, sealant, guide posts, and lifting equipment.
