Overview

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.

Features At A Glance

Increase the Productivity of Your Machine

Two static working positions at 90° and 105°
Closed face design holds fine materials better, provides better retention when working in loose material, and prevents material from packing in the frame.
Expanded machine compatibility range due to a lighter design
Increase the productivity with periodic use where a bucket or rake alone would fall short

More Versatility, More Work Done

Works with bucket or rake to grab, pick, sort, and move materials
Stiff Link Thumbs are universal to across range of bucket sizes, making them easier to pair to buckets in a mixed fleet
Get the best thumb for your tasks. With three tine configurations, select the best option for a wide or narrow grip, shorter center times for straddling the boom during transport.
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 to Operate

Patented alignment system allows for one person to easily deploy or store the thumb
Folds against machine boom for easy storage during travel or other activities
Simple installation, maintenance, and overall operation make thumbs a simpler, more affordable owning and operating choice than grapples

Boost Efficiency and Productivity with Integrated Technology

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.
Track your entire fleet of attachments and machines from one source. View thumbs with asset tracking within VisionLink® alongside Product Link™subscribed equipment.
Keep your assets secure. Thumbs with an asset tracker send an alert if they leave an easy-to-setup site boundary.
