Progressive EZ Link Thumb

Tech Specs

Bucket Compatibility

Pin-on thumbs are made specifically for the bucket they will be used over. For the best customer satisfaction, lowest installation cost and maximum productivity ACS recommends you use an ACS bucket that is specifically designed to fit and work with your thumb. *There is a minimal design charge to adapt this thumb to fit a non-ACS bucket.

Adding a Coupler

ACS will vary the thumb length according to whether or not you plan to use the thumb on a coupler-equipped machine. A thumb on a coupler-equipped excavator needs to be longer in order to interlace correctly with the bucket teeth.

Sizing Your Thumb

ACS attachments are sized based on OEM specifications. View our size chart to determine the correct size for your machine or call our support specialists at 1-800-321-2348.

Features

• Custom Thumb Fit

  Every thumb is custom designed and manufactured to work with the specific geometry of the bucket it will be installed over, so that the teeth interlace evenly and the operator gains the widest range of motion possible in all job applications. Also, ACS will pre-fit your thumb to fit machines that have a coupler installed, including Volvo "S" series couplers.  

• Greater Range of Motion

  The patented design allows for a full 162 degrees of thumb rotation, enabling the thumb to follow the bucket without dropping handled material.

Options

• Custom Thumb Design

  ACS will custom design your Pin-On Thumb to fit another manufacturer's (non-ACS) bucket. A measurement sheet and instructions will be provided for communicating bucket data to our engineering team.

• Serrated or Smooth Teeth

  Serrated teeth provide a more secure grip on the material being handled. Smooth teeth don't mar or cut into the material. We recommend smooth teeth for working with things like logs that will be cut into lumber or stones intended for use in decorative landscaping.
