STAKKAbox™ JMF is a range of modular and structural preformed access chambers that provide a modern alternative to traditionally brick-built chambers. This system provides contractors with a means of constructing access chambers safely, quickly, and inexpensively while offering superior build quality, reduced defects, and enhanced site safety performance over traditional methods.
STAKKAbox™ JMF is designed for use within the telecommunications market and is available in 102, 104, and 106 sizes.
How it's Built
Lightweight 150mm deep sections are stacked on top of each other on a Type 1 base to the desired depth. With no requirement for lifting plant or skilled box builders when building chambers, ring sections can be cut to bridge over or around existing networks or obstacles, making the STAKKAbox™ JMF the ideal all-round chamber system.
'NEW' JMF vs Quad
The new STAKKAbox™ JMF has been designed and developed to provide an enhanced all-round telecom network access chamber system compared with the Quad box.
Its design has been specifically tailored to meet the requirements of installation teams installing the system in a wider range of environments. For further information, visit our FAQ section.
STAKKAbox™ JMF is manufactured from nitrogen-foamed High Density Polyethylene (HDPE), of which up to 90% is recycled material.
HDPE possesses excellent strength to weight properties, and its twinwall design gives it strength while being lightweight for ease of manual handling and installation.
STAKKAbox™ JMF is a modular access chamber available in three sizes: 102, 104, and 106.
All chambers are available with B125 access covers and Cubis' range of chamber accessories for safe access and cable management. Download our product size guide for chambers in order to gain more information on available sizes.
STAKKAbox™ JMF has been extensively tested to ensure that it meets the loading requirements up to B125 in a variety of installation environments.
The loadings match the vertical loading categories recognized by EN124 gully tops and access tops for vehicular and pedestrian users.
