Benefits

Application

Cat® Stiff Link Thumbs are designed to easily handle a wide array of bulky, irregularly shaped objects encountered in demolition, industrial, construction, recycling, storm debris clean-up, landscaping and other aggressive applications.

Adjustable Link

Three position link that allows the thumb to be used with a wide range of varying sized objects.

Durable Tines

Tines made of T1 steel resist bending and abrasion against some of the hardest materials, like rocks or concrete.

Retractable Thumb

Retractable thumb allows normal bucket loading when not in use.

Cross-Tube Design

Maintains rigidity while offering optimized visibility for better site into bucket when lifting irregular loads.

Thumb Tine Spacing

Optimized tine and bucket tooth spacing allows thumb and bucket to mesh together without interference. Different width buckets can be used with the same thumb for maximum flexibility.
