Abstract
Embodiments of a restrictor plate assembly are disclosed that are adapted for being installed into a curb box hood for restricting particulate flow through an inlet mouth of the hood and into a cavity of the hood. An exemplary assembly can include a lengthwise proximate member and a lengthwise distal member which slide lengthwise against each other for increasing a length of the restrictor plate assembly, so that the proximate member can engage a widthwise proximate internal side wall of the hood, and the distal member engages a widthwise distal internal side wall of the hood; thereby securing the restrictor plate assembly within the hood.
