Our 25-1/2 inch composite manhole covers are an ideal direct replacement for 25-1/2″ cast iron manhole covers and 25.5″ CI manhole lids. These ATG-25-1/2″ FRP/GRP composite 25-1/2 inch manhole covers and lids have zero scrap value. Would be thieves simply move on when they find out they are not dealing with common cast iron 25-1/2″ manhole lids. These FRP or Polymer 25-1/2 inch OD manhole lids are much lighter than traditional cast iron manholes of the same size, yet are fully traffic rated (40,000# proof load per AASHTO M-306, H-20). This ATG-25-1/2″ manhole cover measures 25.5 inch outside diameter and fits most 25-3/8″ to 26″ frames. These plastic 25-1/2 in manhole lids improve worker safety and help prevent back and finger injuries that are common with 23 inch cast iron lids.
Our heavy duty 25 1/2 inch (actual diameter) manhole lids feature a diamond pattern slip-resistant surface. The manhole lid is secured using a heavy duty coated worm gear operated by a corrosion resistant pentagon bolt from street level.
