Stiff Link Thumbs
Units: US | Metric- Cat Stiff Link Thumbs are the only thumbs designed to precisely match the working characteristics of Cat Pin-Grabber Quick Couplers and the majority of standard Cat HEX Buckets. This matching means better reliability, better productivity and better customer satisfaction at a very competitive price.
- These thumbs attach to the excavator stick via a multiple position bracket. The thumb can be put in any one of six positions to match differing job requirements or bucket tip radii. When not in use, it can be folded out of the way against the stick.
- Cat Stiff Link Thumbs are engineered and built to perform all day, every day. Ground clearing, scrap loading, light demolition... regardless, the Stiff Link Thumb is ready to take it on.
- Shipped fully assembled, the thumb can be installed by simply welding the bracket to the stick. No special pins, no hydraulics, no fuss, no problems.
