The FiberShield locking manhole cover from McGard is constructed of a durable, fiber-reinforced polymer material with multiple security points, making it lightweight and easy to handle and transport. It eliminates the lifting and dropping injuries caused by heavy, cast iron manhole covers. Weighing 80 percent less than cast iron, it exceeds an H-20 traffic rating. It is installed in seconds and removed without bending over. It requires a McGard key to operate and has no scrap value. 888/888-9192; www.manholelocks.com.
