Features & Benefits

Fast and Easy to Install

STAKKAbox™ chambers are significantly faster to install than conventional alternatives, with complete installations typically taking less than one hour, resulting in reduced costs for the installer.

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.

Sectional & Twin Wall Design

Chambers are built to required depth by adding 25mm or 75mm stackable sections. Due to the twinwall design, individual sections are light meaning that entire chambers can be manually lifted. Each access chamber possesses vertical and horizontal ribs,  resulting in a product that is strong vertically and on the sidewall.

Manufactured from Recycled Material

Specifying STAKKAbox™ Hydrant helps end users reach sustainability targets due to the material being largely composed of high-grade recycled material. In addition, Hydrant is completely recyclable at the end of its life.

Complete System Offering

Can be supplied with D400 surface box or B125 Concrete Infill access cover.

Robust Material

No breakages and therefore lost product when in use and in transit.

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.



The STAKKAbox™ Hydrant system is moulded in talc-filled recycled Polypropylene (PP) which possesses excellent strength to weight properties. Each section is ribbed internally to improve loading performance.
