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.
