Strong and durable security

The DuraShield is the most advanced, high level manhole security device available. Even the most aggressive attacks will be deterred by what many have referred to as a “bank vault door” of protection. Secure your manholes from terrorists, thieves, saboteurs, vandals and protect your system with one strong manhole security device. Access is eliminated, safety is assured and your assets remain locked and protected with the DuraShield manhole security device.

Multiple security points

Other manhole security inserts use only two security points. The DuraShield manhole security device has three, reinforced security points to provide you with unmatched protection. That’s 50% more manhole security than other products.

Easily installed in seconds

Using the McGard Multi-Purpose Tool with your registered key, you can install or remove the DuraShield manhole security device in seconds without ever having to bend over, strain or get on your hands and knees. Unlike other products on the market, the DuraShield manhole security device has no chains, bars or any cumbersome dangling components to hit your shins, ankles or any other part of your body. Watch our video for a quick demonstration.

All stainless steel construction

The DuraShield manhole security device is an extreme duty, all stainless steel security device that will secure your communication vaults, fiber optic cables, distribution valves, grease traps, sewer system, storm drains, electrical lines, steam lines, water lines or virtually any other type of cable, pipe, wire or underground infrastructure accessed through a manhole.

Lightweight — easy to transport

Easily handled with one hand, the DuraShield manhole security device is light enough for any person to carry and install. Security for your manhole opening has never been so easy and convenient.

The DuraShield manhole security device is available with or without slots to provide draining and venting if desired.
