Tri Underground are the exclusive manufacturer and supplier of the TRI TUFF Composite Cover which is available in Type 4, T60 Circular & T100 Circular. This Australian made cover is widely used throughout Queensland for both Main Roads and councils as it lightweight and made from a non-conductive, slip resistant composite material. This is beneficial as no insulated coating is required to make the lids safe and non-conductive. It meets MRTS91 requirements, TMR certified, Class B load rated and can be used in all the same applications as the steel lids.

Customised shackless Padlock-able and customised labelling options are also available upon request for a variety of networks including red light/speed camera lids of the Queensland Police Service. Ask our team to find out more about these.
