Description
Rhin-O-Tuff HD8000 Wire Closer
The Rhin-O-Tuff HD8000 wire closer is a precision-engineered twin loop wire closer designed to perfect the final step in professional wire binding. Built for accuracy, durability, and high-volume performance, the HD8000 ensures consistent and uniform wire closure across the full range of twin loop wire sizes.
Proper wire closure is critical — too loose results in page movement, while over-closing causes overlap and distortion. The HD8000 eliminates both issues with advanced mechanical precision.
Full Wire Size Compatibility
One of the few wire closers capable of handling every available twin loop size:
3/16″, 1/4″, 5/16″, 3/8″, 7/16″, 1/2″, 9/16″, 5/8″,3/4″, 7/8″, 1″, 1-1/4″
From the smallest to the largest diameter, the HD8000 delivers uniform closure.
Dual Adjustment Precision System
Unlike standard wire closers, the HD8000 wire closer features:
Two heavy-duty thumb screws
Independent left and right adjustment
Compensation for gear slippage over time
Correction for uneven closure
This allows operators to fine-tune each side of the wire, ensuring both ends close evenly — a critical feature in high-volume production environments.
Modular or Standalone Operation
The HD8000 offers flexible installation:
✔ Bolt directly onto your Rhin-O-Tuff modular punch
✔ Operate as a standalone wire closer
✔ No additional stands required
Its standalone capability increases speed and workflow flexibility in print shops.
