The bigger brother of the Loos & Co. Professional wire tension gauges the RT10M and RT11M are specifically designed for rod rigging and higher tensions. Easy to use, just slide the rod between the two upper rollers and then pull the spring loaded gauge onto the rod, you will be able to measure accurately rig tension for quick and repeatable tuning. Each model covers a range of approximately 5% to 25% of the breaking strength of the rod with 3% accuracy. Rig tension can be adjusted with the gauge in place.

All models are manufactured of anodized aluminium, are non-corrosive and will give years of service. Detailed operating instructions are included with each tension gauge.
