The GRABO RockSeal™ is built for the surfaces that defeat everything else. This patented seal grips extremely textured, uneven and hard material with a surface profile of up to 10mm, where a standard gasket cannot make proper contact.

Split-face stone, rough concrete, exposed aggregate and heavily textured pavers are the everyday targets. The seal deforms into the profile of the surface and holds a working vacuum, turning your vacuum gripper into a tool that works on the material you actually have rather than the one in the brochure.

Fits the GRABO range. If textured stone is slowing your crew down, this is the single accessory that changes the day, and it is a large part of why these GRABO gripsters and vacuum lifters end up on hardscape sites in the first place. Fit it in place of the standard Type A1 seal and the same gripper handles surfaces that stop an ordinary vacuum lifter dead.
