Pin-Mounted Thumbs


When precision is key, Rockland Manufacturing’s pin-mounted thumb is the perfect tool for the job.  These thumbs allow operators to pick up and move items with pinpoint accuracy and tightly grip objects of all shapes and sizes, even irregularly shaped materials like rocks and branches.

The pivot pin mounts the attachment through the machine’s stick and bucket or coupler for faster, easier installation.

Our pin-mounted thumb is constructed with a rigid box frame and features a rotation of up to 120 degrees.  We designed the thumb tines to mesh perfectly with the bucket’s teeth for a more secure clamp. These rugged thumbs withstand tough jobs with a superior design that lets operators pick up fine materials and place them precisely.
