Four Part Infill Covers (Gastight)

The popularity of larger Pits and enclosures in 1500mm and 2000mm square continues to grow and to reduce leadtimes, Mascot Engineering keep stock of these two popular size 4 part Multipart Covers.

These stocked Multipart Gastight Covers suit approximately a 1500sq and 2000sq opening and are in Class D (load rating as per AS3996:2019) complete with a removable beam to allow full access to the enclosure.

We have the capability to provide these products encased in concrete to ease installation and reduce time spent on site.  We can also manufacture an appropriate Precast Concrete Pit to pair with these covers to your site requirements.  At the bottom of this page, you’ll find a link to our Custom Precast section that covers our manufacturing capabilities.
