Hydraulic Pin-On Thumbs
Maximum grip, fluid motion, and extreme durability.

The Hydraulic Pin-On Thumb is engineered to follow the tip radius of the bucket, ensuring optimal grip throughout the entire range of motion. Mounted directly on the bucket pin, it delivers superior control and strength for high-use environments where versatility and precision are key.

Hydraulic Weld-On Thumbs
Streamlined power for seamless handling.

The Hydraulic Weld-On Thumb offers smooth hydraulic operation with a fixed weld-on mount, delivering strength and flexibility in a compact form. Perfect for operators who need hydraulic performance without the added complexity of a pin-on setup.
Manual Pin-On Thumb
Simple, reliable, and highly effective.

The Manual Pin-On Thumb provides consistent grip with minimal maintenance. Mounted on the bucket pin and adjustable to multiple positions, it offers a cost-effective way to enhance machine functionality on less frequent or lighter-duty jobs.
Manual Weld-On Thumb
Straightforward design with strong performance.

The Manual Weld-On Thumb is the simplest and most budget-friendly model in the lineup — yet it doesn’t compromise on build quality. Welded directly to the excavator stick, it locks into place manually and provides solid support for lighter material handling.
