- Thumbs are equipped with a twist-resistant ‘Inverted Y’ stiff arm
- Expanded range of heavy-duty thumbs permits installation on mini-excavators, rubber-tired back-hoes and excavators
- All steel tines are fabricated with AR400 (abrasion resistant) steel, serrated and gusseted. AR400 is 38% stronger, 46% harder and resists wear better than commonly used T-1 Steel
- Three versatile, ridged positions to adapt to a variety of working conditions
- Pins are machined out of hardened steel alloy
- Overall thumb width never exceeds the carrier’s minimum bucket width eliminating potential interference during operation
- Thumbs fold flush and maintain a low profile when pinned flat against mounting bracket
- No additional parts required to hold thumb in retracted position
