Super Spars Rig Tension Gauge - for 2.5mm - 4mm Wire

Super Spar tension gauge suitable for wire 2.5mm, 3mm and 4mm.

NOTE: This product is only suitable for 1 x 19 wire and NOT Low Stretch 1 x 7 wire.

Manufactured from anodised aluminium, the gauge cannot be left on the shroud when tensioning as it has to be held in position. The gauge comprises two aluminium arms which are fixed together at the bottom end.

The wire is placed in a groove at the bottom end, then the gauge is placed up against the shroud and a piece of string is pulled so that one of the arms extends to a maximum value. The reading is then taken from the other arm on a scale: this reading is then transferred to a scale on the arm which enables the tension, in kg, to be read on the appropriate wire diameter scale.
