SubTerra Axess-PP

Modular access chamber system for cable management

SubTerra Axess-PP is a high quality and easy-to-install modular access chamber system that’s manufactured from 100% recycled polypropylene. Due to the structural twin wall design, these duct access chambers have a high strength performance and are a durable, long life asset.


    Available in a variety of sizes and depths, the SubTerra Axess-PP chambers offer a modular solution that can be supplied as individual 150mm high ring sections or pre-assembled complete chambers.


    Almost any clear opening from 150 x 150mm upwards in increments of 25mm are available to order. 


    SubTerra Axess-PP can be made to order to suit specialist requirements such as non-common sizes, pre-drilled duct entries, fitted ancillaries and riveted bases. Our trained team can assist with bespoke requirements.
