Suitable for use with 110mm drainage structures, this 280mm Chamber Access base with a straight-through inlet is ideal for use with the 280mm Shallow Access Chamber Assembly. It is part of a cost-effective solution which requires only two risers, a chamber base and a lid to comply with the nominal invert depth of 600mm.

Conforming to the requirements of Building Regulations Part H1, when combined with the assembly, this access base includes two socket plugs. It can coordinate with a heavy-duty ribbed riser, which prevents deformation, a double-sealed square cover, which provides a fully airtight unit and a watertight push-fit shallow access chamber.
