Theft prevention hardware for raised grating | Prevents theft by fitting under concrete covers.
Almost all of the grates that are stolen nationwide lack fixed or restraint features. The absence of grates can lead to unexpected accidents such as vehicle rollovers, wheel detachment, and children falling. For raised grates suitable for roadside ditches, variable ditches, and underground ditches, we have solutions that cover about 90% with two types of fittings.
