Air seal carriers allow you to set your vault first and then your lid.
Customers who need to carry and place both air seal and/or regular vaults.
You can put the air seal vault base and tub on the vault in the order in which they will be lowered into the ground.
The Air Seal Carrier Feature:
Keeps you from having to load the base of a air seal vault on the handler first and then the tub, so that when you unload it, you have to put the tub on the ground.
