NL | Narrow Line Straightener
Precision Straightening for High-Tension, Multi-Wire Applications
Product Overview
The Narrow Line Wire Straightener is engineered for precision straightening in compact production environments. Ideal for high-strength cable manufacturing and multi-wire processing, it ensures consistent alignment under high-tension loads.
With left and right-hand models, quick-release levers for rapid changeover, and precision-machined grooved rolls, the Narrow Line Series is built for efficiency and long-term performance in demanding applications. The Narrow Line Straightener is ideal for strand galvanizing or annealing, weaving, or mesh applications. A secondary use is in the oil and gas industries for control line straightening.
