Features & Benefits

Fast & Easy to Install

STAKKAbox™ chambers are significantly faster to install than conventional alternatives, with complete installations typically taking less than one hour. This results in reduced costs for the installer. No specialist equipment or plant is required in order to install the chamber and there is no need for specialist box builders

Sectional & Twin Wall Design

Chambers are built to the required depth by adding 150mm sections. Due to the twinwall design, individual sections are light meaning they can be manually lifted. Each access chamber possesses vertical and horizontal ribs, resulting in a product that is strong vertically and on the sidewall. STAKKAbox™ Quad does not require specialist backfills, reducing installation costs.

Smooth Outer Walls with Lip to ‘Key In’

Gaps in the outer wall will negatively impact the effectiveness of compaction around the chamber. STAKKAbox™ chambers have smooth outer walls and an outer lip which keys into the backfill.

Flexible During Installation

Chambers can be adapted to suit on-site conditions with standard tools to overbuild over existing networks, Introduce duct entries for cable entry and for top-section fine adjustment.

Drop-in Furniture & Steps

Cable management and steps are fitted by dropping the accessories into pre-formed pockets. These allow accessories to be retrofitted after installation without mechanical fixing.

Meets Openreach Quality Requirements

Openreach checks all chambers against 13 step Quality Checklist for its brick, concrete and joint boxes. When using STAKKAbox™ Quad, this checklist is reduced to 8 checks.

All Weather Construction

Unlike with brick-built chambers where freezing temperatures can stop work, STAKKAbox™ Quad can be installed in all types of weather.
