Paving 1 Inch After Risers Are Installed
One Inch Riser Installed
“ I started looking around and discovered the American Highway Products Pivoted Turnbuckle Manhole Riser ,” said Lawrence . The AHP adjustable risers are sturdy , lightweight rings of flexible U . S . steel , joined with turnbuckles that make them easy to expand and contract — with no training required . Using a screwdriver as a lever , a crew member can apply 5,600 pounds of even pressure around the entire circumference of the riser . This enormous force easily , and permanently , fits the riser snugly to the existing frame at the exact height needed to match new road grades . Importantly for Lawrence , they are available in very thin heights and customizable in quarter-inch increments . “ In four years , we ’ ve purchased over 700 American Highway Products risers , mostly in 3 / 4-inch and 1-inch riser heights ,” he says . “ They ’ re high quality , reliable , affordable , and I like that they ’ re made in the USA .” Based in Bolivar , Ohio , AHP was founded in 1978 and has developed a product catalog filled with solutions for nearly any road-leveling challenge . Along with the game-changing Pivoted Turnbuckle Manhole Riser , AHP also offers Inclined Manhole Risers , Catch Basins , Inlet Risers , Valve Box Risers and other products for protecting exposed road work . No matter the product , AHP prides itself on creating solutions that aren ’ t just reliable but also easy to implement . For Lawrence , that made the Pivoted Turnbuckle Manhole Riser stand above its competition during the town ’ s road-leveling project . “ An install literally takes just a minute and a half ,” said Lawrence , a one-man crew who does most of the riser installs himself . “ I clean off the original rim , pop in the riser , and tighten it in .” It ’ s a striking difference between the hours-long process of manually adjusting the casting which often requires a two-man crew .
Typically applied in one-inch thicknesses , sometimes ¾ ”
“ Honestly , it ’ s kind of thrilling ,” said Lawrence . “ And I ’ ve never had one come out ! The American Highway Products riser is a great product , with great results , and makes for a great road !”
