You've got a paving project pending. You know that using riser rings to lift the manhole covers to grade will make your job not only easier but also better. You need a riser that has hung around the urban streets for many years and knows what the streets are like. You need a riser ring that is good quality - like grade A36 steel. You need it to be custom made because there are thousands of different sized manhole openings in this country. You need bituminous asphalt paint to protect the metal. You need stainless steel locking devices to smooth the constantly growing flow of traffic. You need durability for all the weather El Nino can toss around. And you need the risers ASAP.
