The USA ATTACHMENTS THL Thumb Long is a quick coupler style thumb designed for the SY35U compact excavator. A thumb works with the bucket to grip and hold material, turning the excavator's digging arm into a tool that can grab, pick, and place objects instead of only scooping them. The long thumb configuration is commonly used where a larger gripping span is helpful.

Adding a thumb improves versatility on the job site. Operators can handle irregular or bulky items such as logs, brush, rocks, concrete pieces, pipe, and demolition debris with more control. This reduces the need for a second machine or manual labor for sorting and loading tasks, and it helps keep material secure while it is moved. The long thumb style gives added reach over the bucket for gripping larger items.

The product information identifies this unit as a long thumb for use with a quick coupler on the SY35U. No further specifications such as weight, dimensions, or material grade were provided, so buyers should confirm fitment and details with the seller before purchase. In general, excavator thumbs are made of welded steel and mount to the stick, working in coordination with the bucket through the machine's hydraulic controls.

This attachment suits excavation contractors, landscapers, utility crews, demolition contractors, land clearing operators, and site preparation companies. Fleet managers and rental managers may also value it for expanding the range of work a compact excavator can perform.
