Limit Access with The ManLock
Secure your cast iron cover to its frame with McGard’s ManLock high security lock bolts to keep out intruders. Simple yet effective manhole security by way of a patterned bolt head helps to prevent unwanted access to any manhole cover, drainage grate, steel access panel or hinged vault door.
Replace your existing cast iron cover bolts or modify your ring and cover to accept our bolt. Terrorists don’t have a chance once you install these ultra high security locks. The Intimidator ManLocks are used to satisfy the security requirements of the Federal Aviation Administration (FAA), the Federal Bureau of Prisons (FBOP) and many other military and government agency physical security requirements.
