Figure 7-28 — Spiked Guylines and Skylines Anchor [Figure not included. See ED. NOTE.] (2) All the bark must be removed from the stump where the line is wrapped and spiked. (3) Employees must not stand close to the stump or tree or in the bight of the lines as the guyline or skyline wraps are being tightened. (4) When removing spiked guylines or spiked skylines from stumps or trees, a reverse safety wrap (Figure 7-29) must be put on and secured before loosening the last wrap, or the skyline or guyline must be held while the spikes are removed from the last wrap, and snubbed until the tension is relieved.
