Rock Seal for GRABO


The GRABO Rock Seal is designed to make it easier to pick up rough materials such as rocks, stones or surfaces with variations in height up to 10mm.

The Rock Seal is made from durable, extra thick foam, allowing it to form a strong seal around uneven material. Rock Seal is compatible with all GRABO models and can be swapped from the standard GRABO seal in seconds.
