Walls really liked the patented pivoted turnbuckle adjusting mechanisms that links the durable steel rings of which the risers are made—he felt they were stronger, easier to adjust, and seated the risers more tightly in original utility rims than every other adjusting mechanism available.
Shortly before his retirement in 2012, Walls concluded, “Our manhole ring problems have been zero—so far, in 18 years, every one we have installed is still there! Not one has come loose or been broken.”
Ten years later, Romero agrees. “They hold up well,” he says. “And in emergencies, like we had on Fairfax Blvd recently where an old cast iron riser dislodged, they’re so fast to install! That time, we got the call, drove back to the shop to get the right-sized riser, and had the new riser installed and manhole secured in less than an hour.”
In Fairfax, American Highway Products Pivoted Turnbuckle Risers have been staying strong and saving time and labor on roadway paving projects for 30 years.
