No Mystery Metal, No Disappearing Seller

Skip the Amazon thumb that shows up with the wrong pin pattern and a seller who's already deactivated their listing. Forge & Grit carries vetted Geith attachments through authorized US dealers—real steel, real warranty, real phone number if something goes sideways. Before any thumb ships, we run your excavator's weight class and coupler type through our Fitment Checker so you know it bolts up the day it arrives. This isn't a guessing game with your freight dollar. This is a vetted attachment matched to your exact machine, backed by a fit guarantee that means we eat the return freight if we get it wrong.

Grab Material Without Running a Single Line

Most mechanical thumbs force you to drill, weld, or reroute lines before you can use them. The Easi-Klamp mounts directly—no extra hydraulics, no weekend spent bleeding circuits. Three pre-set positions let you go from picking rocks to setting pipe without leaving the cab. The oversized pivot pin keeps the thumb rigid under load instead of flopping around like the stamped-steel imports. For an operator who needs to switch between digging and handling on the same job, this thumb turns a two-machine setup into a one-machine workflow. Solid craftsmanship that respects your time on the jobsite.

One Thumb, Four Weight Classes Covered

Whether you're running a three-ton mini or a thirty-eight-ton excavator, the Easi-Klamp comes sized for your machine. The solid base plate and reinforced structure handle the torque that lighter thumbs can't—no bending the first time you pinch a concrete chunk. Available in configurations for both standard bucket setups and machines running a coupler, so you don't have to modify your existing setup. This is an investment in an attachment that scales with your fleet instead of sitting in the yard because it only fits one rig. Forge & Grit confirms your weight class and coupler style before it ships.

Check Your Fitment

Confirm your excavator matches the supported configurations before ordering. Not sure? We'll verify it for you.

  • Excavator weight class falls within 3-4, 4-6, 7-8, or 35-38 ton range
  • Machine matches selected coupler configuration (no coupler or with coupler)
  • Boom mounting area is clear and accessible for bolt-on installation

Built for Real Jobsite Work

This mechanical thumb handles the tasks where a bucket alone comes up short.
