Rapid installation
STAKKAbox™ chambers are significantly faster to install than conventional alternatives. Complete installations typically take less than one hour — resulting in reduced costs for the installer.

Light but strong
Twin-wall construction keeps each section lightweight for manual handling. Each access chamber has vertical and horizontal ribs, resulting in exceptional strength in vertical and sidewall loading.
