Three Part Infill Covers (Gastight)

Mascot Engineering’s Three Part Covers combine three standard size covers in a single frame.  These covers are used when a single part does not provide a large enough clear opening or when smaller individual covers are required to ease lifting.

A range of Class E (400Kn) Three Part Infill Covers are also available. The chart below will be updated shortly, in the meantime please contact us for details.
