Utility Security Locks

SEWERLOCK security barriers are custom manufactured to lock underground utilities in manholes and communication vaults for cables and other power systems. The subframe and inner cover prevents vandals from tampering with wire and cables. The barrier can be installed into any size or shape utility opening without modifying the structure or cover. 

The stainless steel products will not interfere with your power and communication wiring systems. All of our products provide security so people cannot fall into unprotected manholes while also preventing items from being thrown into them.
