Clark Vaults…Every Clark vault is engineered to protect the casket from the outside elements through the use of an air seal principle. This can be easily demonstrated by turning a glass upside down and then submerging the glass into water. The air trapped inside the glass prevents the water from rising more than a fraction of an inch. The same is true of a non-porous Clark metal vault. The air trapped inside the dome prevents outside elements from reaching the casket.
Each vault below offers different levels of protection with the unique materials used.
