To keep equipment safe from water and unauthorized entry, and to avoid stray voltage from manhole lids, Hamilton Kent provides The Lifespan System.
This manhole frame and cover system is completely watertight to eliminate inflow; it accommodates freeze and thaw cycles to prevent cracking around the pavement; and its lock-down cover deters people from getting into the vault.
