A system and method are provided for coupling a manhole cover to an underground utility box to support the manhole cover substantially flush with a ground surface such as a roadway. A holder couples to an underground utility box and includes upper and lower ends and a channel extending therebetween, and a support structure extending into the channel and defining an upwardly facing support surface. An adjustment member for coupling to a manhole cover is inserted within the channel, and includes upper and lower ends, and a passageway extending therebetween and communicating with the channel. The adjustment member is movably receivable within the channel to be seated on the support surface, and to define an adjustment space between the adjustment member and the holder. The adjustment member may thus be adjusted for accommodating a slope and elevation of a ground surface, and sealed with the holder after adjustment.
