Loos Pro Rig Tension Gauge Large - Professional Model, Cable Size 7-10mm

The Loos “Professional Model” tension gauge is designed to provide an accurate measurement of the tension in rigging wire and other types of cable used in recreational and industrial applications.

It is particularly used for accurate and repeatable tuning of a sailboat’s standing rigging.

Each model covers a tension range of approximately 5% to 25% of the breaking strength of the wire and is designed and tested to provide an accuracy of plus or minus 3% at mid-range.

The “Professional Model” tension gauges will provide an increase in accuracy and convenience of use when compared to our popular standard gauges, Model A and B. The gauge may be hooked on the wire and will remain in position while the tension is adjusted.

How to measure rig tension with the Loos Gauge:

1. Hold the gauge with the left hand and place the cable between the two nylon spools.

2. With the right hand pull the lanyard and extend the spring until the hook on the nylon slider can be hooked on the cable.

3. Release the lanyard to assure accurate readings make sure that the slider moves freely in the frame slot and does not bind, move frame back and forth to center it.

Also, lubricate the slider slot frequently with silicone lubricant. Read the needle position on the scale. Refer to the calibration table to obtain correct tension in the cable. The gauge can be left on the wire for “hands free” adjusting of the cable.

Note.
An extra 1/4” inch hole is provided in the frame of the instrument for an attachment of a short lanyard and snap hook (not furnished) for securing the gauge to the cable. This will prevent loss of the instrument if it becomes inadvertently detached.
