Lift & Lock Improves
Manhole Cover Security
Manhole cover security is a key part of preventing terrorist access to our underground sewer passages. The only thing currently impeding access is the 150 pound weight of the manhole cover itself. This does not present a suitable barrier. As Americans, we use special keyed bolts to prevent thieves from stealing our automobile tires, but we aren't doing enough to secure the underground passages of our cities.
Lift & Lock is a carefully designed solution for both manhole cover security and worker safety
In addition to its many safety features, Lift & Lock contains
patented lock bolts to ensure manhole cover security. Arthur A. Schrage, a sanitary
engineering consultant with over 30 years of experience, designed Lift & Lock specifically
to serve the needs of cities and utilities. Lift & Lock manhole
covers work well in just about any application that uses a regular manhole cover...
from gate wells on water systems to telephone
utility vaults.
The standard Lift & Lock Manhole Cover design contains 3-4 locking bolts that require a special wrench to loosen. Standard wrenches and sockets will not turn the bolt, and the manhole cover will not open until the bolts have been loosened. Learn more about this patented design for improved manhole cover safety.
Implement Lift & Lock Quickly and Easily
You can purchase new manhole covers or retrofit existing manhole covers, depending on your needs. Lift & Lock does not require removal of any part of the manhole itself. Please review the features of the design more closely, or
