The Man Pan Classic manhole insert is strong and easy for field staff to handle. Its reverse-arch bottom provides strength and holds less water, which puts less stress on the insert. Lifting lugs make it easy for field staff to install and remove the unit with a pick or a J-hook. Its standard gasket provides an extra barrier to inflow and helps control odor. The unit is made from high-density polyethylene for forgiveness and corrosion resistance, and comes trimmed to order after a review of the user’s needs. 724/942-9500; www.themanpan.com.
