Excavator Manual Rock Grabs

The only Fully Adjustable Manual Rock Grab on the market to suit all machines. One attachment to fit multiple machines. Uniquely designed heavy-duty Rock Grab features reinforced plating, hard-faced tips, and a five-finger interlocking design for a secure grip on even the most challenging materials. A quick-release arm allows for fast installation and removal, keeping downtime to a minimum and productivity at its peak.

Unlike standard excavator grabs, ours features fully adjustable ears, making it compatible with virtually any excavator model. With a one-time setup tailored to your machine’s specs, you’re ready to tackle a wide range of tasks—from demolition and sorting to land clearing—with confidence.

When you upgrade your excavator, there’s no need to buy a new grab. Simply resize the ears and adjust the pin size (within range) to suit your new machine, saving you time and money while maximising equipment lifespan.

Proudly Australian-owned and operated, Adjustabucket designs and manufactures patented excavator attachments that deliver unmatched durability, efficiency, and adaptability on every job.

Also referred to as a Mechanical Grab, Static Grab, or Stiff Arm Grab, the Manual Rock Grab is a proven performer in tough working environments.
