The Basic Urn Vault Double Size – Gray is a sturdy container designed to hold two cremation urns (or a larger size cremation urn that won’t fit in the single size) that are intended for earth burial. Any type of urns can be placed in the vault (wood, ceramic, brass, etc.). Typical metal cremation urns would be placed side by side in an upright position as shown in the image. Other small mementos can be included in this container if desired. A water-tight adhesive is provided to seal the urns within the vault. Many cemeteries require the use of an urn vault to protect urns and their contents from the elements as well as from possible damage from heavy cemetery equipment. The urn vault is constructed of a high tech polymer to maximize strength and durability and has been tested to withstand 4,300 psi. The color is a mottled gray pattern that is meant to look like granite. The vault will not corrode or deteriorate. Made in USA.
