ALLYN FABRICATION · WASHOUGAL, WASHINGTON

Custom excavator attachments.
Built around your machine.

AllynFab LLC designs and fabricates excavator attachments for the machine, connection and work you describe. We specialize in attachments with the WSM Coupler. Based in Washougal, Washington, we ship custom builds nationwide.

Rakes, rippers, buckets and thumb components

A useful attachment starts with the work it needs to do. Tell us what material you handle, how you use your excavator and which features matter to your project. We can discuss a custom build instead of relying only on a catalog size.

Excavator rakes & rippers

Custom rake and ripper fabrication matched to your excavator and intended use. Include the working width, tooth layout or other requirements you want us to review.

Buckets & thumb components

Discuss custom bucket dimensions and hydraulic or mechanical thumb components. Thumb length and width at the tips help define the fit and working geometry.

WSM Coupler attachments & mounts

We specialize in attachments with the WSM Coupler, alongside custom pin-on and quick-coupler configurations, mounting ears and connection components. Share your coupler make, model and reference photos so we can review the connection.

Fitment details we need

Two machines with similar sizes can use different pins and mounting dimensions. Our build request and measurement form collects machine make and model, pin diameters, pin center-to-center distances, stick or ear width, attachment width and coupler information. Millimeters are preferred; inch measurements are also supported.

For a thumb build, use the diagram on the form to identify the thumb length measurement points, and include the thumb width at the tips. Photos of the existing bucket, stick and coupler help explain details that a measurement alone can miss.

From your measurements to a build request

  1. Describe the attachment, machine and work you need it for.
  2. Measure the connection and add clear reference photos.
  3. Send your request so AllynFab can review the scope, fitment and delivery details with you.

Pricing, build time and shipping arrangements depend on the project. Contact us for the details of your build rather than assuming a standard lead time or shipping cost.

Made in Washougal. Shipped nationwide.

We work with attachment customers across the United States. Include your delivery location when requesting a quote so shipping can be discussed along with the build.
