Placing Lid in Pivoted Turnbuckle Manhole Riser started using American Highway Products Pivoted Turnbuckle Manhole Risers . “ The improvement for us was a lower cost for a better-quality product ,” said owner Bo DePuy . “ We were using cast iron rims before , and sometimes they just didn ’ t fit well . We haven ’ t had that problem — or any problem , really — with risers from American Highway Products .”
Ultimately , the AHP manhole risers ’ precise fit and adjustability were attractive features for DePuy , but they first had to prove they were up to the job . “ I was worried at first about getting a good fit ; on the job , we pull out any existing risers and need the new risers to fit the original rim and match the new pavement ,” said DePuy . “ I was also worried about the turnbuckle adjustment mechanism and wondered if it would cause problems .” But after several installations , DePuy realized that precision and durability weren ’ t problems at all . “ They ’ re great products ,” said DePuy . American Highway Products risers are available in incremental sizes , making it easy to order solutions that are exact matches for the manholes DePuy routinely raises in Ohio . And the patented pivoted turnbuckle is an excellent solution for another challenge paving companies often face ; using a screwdriver as a lever , the turnbuckle can expand or contract the riser roughly half an inch in either direction to slip the riser precisely into the existing rim — even if the rim is worn or out-of-round . And the turnbuckle can also be tightened down ; the lever exerts thousands of pounds of mechanical force to seat the riser securely and permanently in the rim , able to stand up to traffic and even the occasional snowplow blade .

DePuy Paving also uses AHP ’ s Catch Basin and Expandable Valve Box risers , which depend on precision manufacturing to achieve precise , tight fits . He said he likes the products so much , and has so much confidence in their quality , that he orders nearly 200 a year in various sizes and stockpiles them to use as needed during the paving season . “ They don ’ t rust , and one guy is able to have them on his truck and do all installing ,” said DePuy . “ For us , it ’ s a much better way to do things .”
