Type 45 Steel PowerLok lid (AS 3996 Class B)



The Type 45 Steel PowerLok® (AS 3996 Class B) is a steel cover designed to comply with Australian Standard AS 3996 for load-rated covers and frames. It consists of two parts that fit together to create a tight seal, and its PowerLok® feature ensures that it remains securely in place, even under load. ACO Polycrete’s innovative PowerLok® barless locking system provides a highly secure method of locking the lid to the pit through a fastened bracket, without the need for a low hanging locking bar. The system features a bolt or padlock provision for high-security areas and is engineered for easy accessibility and safety.
