BT / Openreach Quadbox Duct Chamber 1310mm x 610mm x 150mm

Description The BT / Openreach Quadbox Duct Chamber 1310mm x 610mm x 150mm is a large-format modular chamber for use in underground telecom and utility networks. Approved for use in Openreach infrastructure, it is ideal for full-fibre rollouts, jointing enclosures, and high-capacity duct access points. Each unit is made from twinwall polypropylene and supplied in 150mm deep stackable sections. These interlock to provide a stable, secure structure that can be installed quickly without the need for brickwork or wet trades. This reduces time on site and ensures consistent build quality. With internal dimensions of 1310mm x 610mm and a section weight of 16.2kg, this size offers a spacious working area for complex cable routing and large splice closures. While still suitable for manual handling by two-person teams, the added internal volume makes it ideal for access points that require more internal flexibility or multiple duct entries. The chamber includes pre-formed pockets in the sidewalls for drop-in accessories, such as cable bearers, corner steps, and sub-security plates. Duct entries can be created using a hole saw, with integrated guides ensuring proper spacing and alignment. It can be built on a compacted Type 1 or dry mix concrete base, in line with Openreach guidelines. Covers and security options are available to complete a fully integrated quadbox system, with B125 load-rated options for footway applications.
