The Blue Diamond® Thumbs are available in a wide variety of sizes to meet any demand. The back plate welds onto your excavator’s dipper stick and has multiple positions for the stiff arm to give you the best grip on whatever material you are working with. When not in use, the stiff arm or cylinder can be removed and the claw will sit against the dipper stick out of the way.

Features Include

  • Welds onto any excavator
  • Multiple positioning for best angle to grab
  • Stiff arm can be removed to store claw flat against the dipper stick
  • Does not require any OEM mounting brackets

    Use the size chart to determine witch thumb you need.

    NOTE: This chart is for manual models and is intended as a guide only. Due to the many differences in machines and accessories, it is the customer’s responsibility to choose the right size of thumb for their application. Typically, the length of the thumb must meet or exceed the measurement from the tip of the bucket teeth to the bucket pivot point.
