Protect underground assets from surface water, spills, dirt and debris
Inflow causes extra expense and jeopardizes your reputation. Manholes are access points to your sanitary and storm sewer systems. They are also a source of inflow—undesirable water and debris adding to your operating costs. There is one decision you can make to eliminate your inflow problem for good: choose the patented LockDry device.
The LockDry is ideal for vaults that don’t need to be secured, but need to be kept free of water and debris. The device uses a neoprene compression gasket to form a tight seal with the top of the manhole frame. This blocks surface water, dirt, debris, fats, oils and greases from entering manholes or vaults.

The device uses a neoprene compression gasket to form a tight seal with the top of the manhole frame. This blocks surface water, dirt, debris, fats, oils and greases from entering manholes or vaults.
Keeping surface contaminants out reduces waste treatment costs. Dry vaults do not need to be pumped out prior to any maintenance work. Keeping water out of the vault reduces the risk of damage to critical infrastructure.
The pan weighs less than 40 pounds and will fit any existing manhole frame (no modification to the frame or vault needed). A stainless steel handle provides fast and easy drop in and lift out.
Sizes range from 20” to 38”
The device can be outfitted with a gas detection port with a self-sealing rubber grommet. This keeps the vault free from inflow but allows maintenance personnel to test for gas before entering the vault.
Our pans are spun from 16-gauge spun so they won’t corrode, warp or split. Unlike plastic and rubber, they do not become brittle or misshapen over time.
If security is a concern, the LockDown device offers all of the above with the added benefit of protection against unauthorized entry.
