Large Snorkel Vault Extension

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.
