The Snorkel® Vault Extension V2 allows you to increase the installation depth of your wetland filter without losing convenient surface access for maintenance. 

By securely locking onto the top of the Snorkel® Vault*, using one or more extensions allows for deeper excavation depths, ideal when adding extra layers of gravel or stacking additional FilterBlox™ Modules for higher-capacity filtration. 

It is built from the same rugged, rotationally molded material, giving it the strength to support the weight of stone, gravel, and foot traffic above.

Key features:

    Increases Snorkel® Vault* height for deeper wetland filter installations.
    Ideal for extra gravel layers or stacked FilterBlox™ Modules to boost filtration capacity.
    Securely locks to Snorkel® Vault* for fast, reliable installation.
    Add one or more extensions, each increasing Snorkel® Vault* depth by 9.5″ (24 cm).
