Industrial-Grade Precision for Perfect Twin-Loop (Wire-O) Finishing

Precision is the difference between a "homemade" look and a retail-quality document. The Rhin-O-Tuff Onyx HD8000 is an elite, 14-inch electric wire closer engineered to deliver a flawless, circular finish on all Twin-Loop (Wire-O) documents. Built for the high-volume production environment, this standalone unit eliminates the inconsistency of manual levers, providing uniform pressure across the entire length of the wire—even on the thickest 1-1/4" manuals.

With its heavy-duty motor and "set-it-and-forget-it" adjustment scale, the HD8000 is designed to bridge the gap between desktop binding and commercial-scale production. Whether you are finishing 3:1 or 2:1 pitch wires, this machine ensures that every document opens flat and turns smoothly, providing the high-end executive look your clients demand.

Why the Onyx HD8000 is the Commercial Choice:

• Uniform Pressure Technology: Unlike manual closers that apply pressure unevenly from one side, the electric drive of the HD8000 ensures even compression across the full 14" width, preventing "pinched" or "flared" wire ends.

• Dual-Operation Versatility: Features both a standalone finger switch and a commercial-grade foot pedal, allowing the operator to choose the most efficient workflow for the job at hand.

• Precision Adjustment Scale: The easy-to-read sizing scale allows for micro-adjustments, ensuring a perfect close for every wire diameter from 3/16" up to 1-1/4".

• Safety-First Engineering: Includes a built-in safety shield to protect the operator during the closing cycle without obstructing the view of the document alignment.

• Indestructible Build: Proudly manufactured with Rhin-O-Tuff’s legendary all-metal construction, designed for 24/7 reliability in the most demanding print shops and bindery environments.
