Loos Tension Gauge PT3M (7mm - 10mm)

The Loos PT3M is a professional tension gauge designed for 7mm to 10mm wire rigging, offering precise and repeatable tension measurements. Ideal for sailboat standing rigging and other high-load cable applications, this tool ensures optimal rig tuning for both performance and safety.

Key Features:

• High Accuracy – ±3% at mid-range for precise tension adjustments.
• Wide Tension Range – Measures 5% to 25% of the wire’s breaking strength.
• Hands-Free Operation – Stays in place on the wire for easy adjustments.
• Robust & Reliable – Built to withstand marine environments for long-term use.

Why Proper Tension Matters

Correct rigging tension enhances sail shape, stability, and boat handling while preventing structural damage. A slack rig can lead to excessive mast movement, while over-tightening may cause wire stretch or mast damage.

Simple Operation

1. Hook the gauge onto the wire.
2. Pull the lanyard to engage the slider.
3. Release and read the tension.
4. Adjust rigging as needed.

Used by sailors and riggers worldwide, the Loos PT3M ensures consistent and accurate rig tuning for maximum performance.
