The KS ALU 250 inspection chamber is fabricated from a perforated aluminium sheet with opening/lockable lid and is used for intensive and extensive soft landscaping, as well as ballasted inverted roofs. A simple on-site modification allows the unit to be used over outlets that are located close to wall or kerb abutments.

The KS ALU 250 is suitable for landscaping depths of less than 100 mm. Where landscaping is deeper than 100mm, the 50 mm or 100 mm height adaptors can be added as necessary to achieve the required height to be level with or slightly proud of the surrounding landscaping.
