Amulet offers the Best Rigid Universal Thumb – B.R.U.T. for an excellent alternative for backhoe loader and small excavator owners looking for a thumb that is heavy duty in design and easy to install and use. Built to excel in demolition, rip rap, land clearing, scrap, etc. the CT Series thumbs are designed for those who are unable to, or do not require the use of hydraulic thumbs. When not in use, all CT model thumbs are designed to store as complete units tightly against the dipper. The CT stands for “Convertible Thumb”, which allows the rigid, 4-position model to be converted to hydraulic at a later time by replacing the telescopic strut with a hydraulic cylinder.
