BT-H Hydraulic Thumbs have been the thumb of choice for thousands of contractors. They deliver more value than any other thumb. The positive three-point grip is just like picking up something with your thumb and first two fingers. The narrow design keeps thumb weight to a minimum for greater lift capacity.

Description

  • Built-in cylinder guard for cylinder rod protection.
  • Thumb lock - this small but important feature eliminates thumb down drift, thumb jiggle, and accelerated pin wear.
  • Sealed and lubricated replaceable, heat-treated bushings and pins.
  • Easy transport. Transport your excavator anywhere without having to remove your thumb! Rockland thumbs will never hit your excavator's boom. Guaranteed!
  • Easy installation. Thumb pad simply mounts to the excavator's stick and then hydraulics are connected.
  • Available in a wide variety of widths and sizes to suit any application.
  • Designed to match the performance capabilities of your excavator or backhoe.

Warranty

Rockland Thumbs Buckets are guaranteed against failure due to defective design, materials, or workmanship for a period of one year or 2,000 hours.
