The Farr 40 “Rig Spanner” kit comprises of spanners to adjust the V1s, D1s and D2s. The heads of the spanners are angled to allow the easy adjustment of the Turnbuckles. Made from Series 7000 Aluminum, the outside of the Rig Spanner is water cut whilst the internal jaws are milled to suit the turnbuckles; the spanners are anodized to prevent corrosion. The Rig Spanner makes the quick adjustment of the rig a simple practice with clear labeling of the jaws to make them easy to match to each turnbuckle size when endeavoring to carry out rig adjustments in a short period of time.
