Get the most out of your sailboat with the Loos PT series of gauges. These gauges are designed for setting the proper tension in the standing rigging of sailboats and can measure the tension in cables and rods from 2.5 mm to 10 mm. The gauges are relatively inexpensive and are designed to be suitable for rugged marine service. The "Professional Models" provide an increasing durability, accuracy and convenience of use when compared to our popular standard models. The gauge may be hooked on the wire and will remain in position while the tension is adjusted. Manufactured of rugged anodized aluminum, this gauge is corrosive resistant and will give years of service. Detailed operating instructions are included with each tension gauge.
