Features & Benefits
Fast & Easy to Install
STAKKAbox™ chambers are significantly faster to install than conventional alternatives, with complete installations typically taking up to 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 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. 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.
All Weather Construction
Unlike with brick-built chambers where freezing temperatures can stop work, Quad can be installed in all types of weather.
Meets Openreach Quality Checklist Requirements
Openreach checks all chambers against 13 step Quality Checklist for its brick, concrete and Quad joint boxes. When using Quad, this checklist is reduced to 8 checks.
How It Works
Lightweight 150mm deep sections are stacked on top of a concrete or Type 1 base to build the chamber to the desired depth. There is no requirement for lifting plant or skilled box builders when building chambers.
Where required, rings can be cut to bridge over or around existing networks or obstacles.
STAKKAbox™ Quad is manufactured in nitrogen-foamed High Density Polyethylene (HDPE), of which up to 70% is recycled material.
