Stop Guessing What Fits Your Rig

Amazon listings for hydraulic thumbs never list your excavator's pin size, boom width, or coupler compatibility. You order, wait a week, and the bracket doesn't line up. Forge & Grit runs every Geith Klamp Thumb through our Fitment Checker before it ships — verified against your exact make, model, and weight class from 4 to 22 tons. No coupler or direct-mount options covered. If it shows up and doesn't bolt on, we pay freight both ways. No restocking fee. No runaround.

Bolt On Without Pulling Your Main Pin

Most hydraulic thumbs require you to pull the main bucket pin — which means draining hydraulic lines, finding a press, and losing half a day on setup. The Geith Klamp Thumb attaches without main pin removal on excavators from 9,000 to 65,000 lbs. Reinforced pivot area and advanced hydraulics give you smooth, repeatable clamping force every cycle. Less wrench time, more digging time.

Serrated Grip Holds Irregular Loads Steady

Picking up concrete debris, brush piles, or broken pipe with a bucket alone wastes time and risks dropping material back into the trench. The Geith Klamp Thumb uses a durable serrated gripping surface that locks onto odd-shaped loads and holds them through the full swing. It's the kind of craftsmanship that lets you clear a site in one pass instead of three. Built for the jobsite, not the showroom.

Know Your Fit Before It Ships

We confirm your excavator's weight class and coupler setup before this thumb leaves the warehouse. No guessing, no return freight on your dime.

  • Excavator weight falls within 4–22 ton range
  • Machine equipped with auxiliary hydraulic circuit
  • Attachment style matches your coupler setup (with or without coupler)

Built for Real Jobsite Work

Wherever your excavator goes, the Klamp Thumb turns a bucket into a grappling machine.

“Bolted this onto my CAT 316 in about 45 minutes without pulling the main pin. Serrated grip holds concrete chunks and brush piles solid through the full swing. First hydraulic thumb I've owned that actually works like it should.”
