Description Standard Size, Maximum Air Flow. The GRABO HIGHFLOW Oval Open Cell Foam Seal is specifically designed to match the original oval-shaped base of your GRABO HIGH FLOW tool, providing optimal gripping performance on smaller porous surfaces. Unlike closed-cell foam—which creates a complete airtight seal—open-cell foam allows airflow through the material, essential for the high airflow rate of the GRABO HIGH FLOW. This ensures effective gripping without forming a complete vacuum, making it ideal for delicate, porous materials that require specialized handling. Capable of safely holding materials up to 75 lbs (34 kg), it's your go-to seal for lifting smaller pavers, bricks, and textured surfaces reliably and efficiently.
