Trench Runs (Gastight)
Mascot Engineering’s Trench Covers combine any number of standard size covers in a long single frame. Trench runs are used when a single part does not provide a large enough clear opening or when smaller individual covers are required to ease lifting and access. Designed to meet the load ratings specified in AS3996:2019, continuous trench runs can be used to cover and provide access to underground fuel lines, stormwater or sewer systems, electricity and communications enclosures and ducting, valves and many more.
All covers in the system can be removed to provide unrestricted access… alternatively one cover (in any part of the system) can be removed to provide access to a specific section.
Available in Class B, D, E and G (AS3996:2019) all Mascot Engineering access covers are load tested whilst supported on only two sides to ensure no loss of rating when used in a trench run or multipart system.
The chart below will be updated with Class E covers shortly, in the meantime please contact us for details.
