ASSEMBLY BENEFITS
BUILDING SITE EFFICIENCES
Featuring five inlets, the Chamber Base allows for multiple connections and variation in direction reducing the need for a large number of base variants
- Streamlines stockholding requirements
- Providing a singular solution simplifying on site installation
ON-SITE FLEXIBILITY
The adjustable 110mm deep spigot on the cover frame provides more flexibility at installation
- Height adjustments can be made to achieve alignment with finished ground level
- The frame can be tilted for installation in slopes of up to 15°
There is a choice of two covers for either pedestrian or driveway use
STRENGTH AND DURABILITY
Robust ribbed riser for added strength
Manufactured from durable polypropylene and PVC
Heavier cover option for driveway use
INVERTS
Maximum invert depth of 600mm achieved with chamber base, two risers, cover and frame
