▼Installing Cable Trees

Note – Two people are required to install the cable trees. One person must hold the weight of the tree for an extended time.

1.Identify the cable trees.

The cable trees are symmetrical and their orientation for installation can be difficult to determine. When properly installed, the fluted branches of the tree point forward, with the fluting on the underside of the branches. The top surface of all branches is smooth. See FIGURE 2-13.
