Saku® - Solid top thermoplastic access covers

ACO’s Saku® cover and frame system is designed to comply with Australian urban industry requirements.

The product consists of a lightweight thermoplastic cover and ductile iron frame with an EPDM rubber seal. Optional HDPE riser (make-up) rings may be used to raise the access cover to finished surface levels. The Saku® cover and frame system has been appraised by the Water Services Association of Australia (WSAA). The cover lifting weight is less than 9kg, minimising lifting injuries.

The system meets stringent testing for impact and sustained loads for Class B (AS 3996). Manufactured from durable polypropylene, the cover is ideal for corrosive sewer environments, seaside applications and is gas and watertight to AS 3996.
