2025 Caterpillar Stiff Link Thumbs 345 mm (14 in): 589-8364 539 lb

Cat® Stiff Link Thumbs are the ideal add-on to add versatility to your Cat machines. Designed for specific excavator and bucket combinations, they help you take on more materials without compromising fuel efficiency. We built them to upgrade your machine to handle larger, bulkier materials.

• Closed face design holds fine materials better, provides better retention when working in loose material, and prevents material from packing in the frame.

• Stiff Link Thumbs are universal to across range of bucket sizes, making them easier to pair to buckets in a mixed fleet

• Managing multiple attachments for a fleet is easier with a coupler system. Select thumb models are compatible with Cat Pin Grabber Couplers, allowing for machines of similar sizes to share thumbs and other attachments.

• Simple installation, maintenance, and overall operation make thumbs a simpler, more affordable owning and operating choice than grapples

• Never waste time looking for your thumbs again. Cat asset tracking is available for your attachments or anything in your fleet you need to track.
