GMS Grates and Frames

Mascot Engineering’s GMS Sump Grates and Frames come in a range of standard sizes to suit our Glass Reinforced Concrete (GRC) Pits. This range of Grates come complete with the distinctive RHS locater which locks the frame into the pit rebate – simply drop on top, walk away with confidence that the grate and frame will be square to the pit opening.

All are fitted with boltdown facility and are also available encased in an engineered concrete surround / plinth to suit all load ratings. Below you’ll find the standard stock sizes, however we can manufacture custom grating sizes for your project.

Heelproof versions of these grates are also available.
