Note
Set all spring hangers in accordance with setting table. Settings are calculated for mean temperature of 50°F (10°C). Differences in settings are small; all hangers within any one system can be used with same settings. See Figure 1.
Hanger Installation
Begin assembly of transmission line hangers with rigid hanger, followed by spring hangers. Bolt spring hangers directly to tower at 10 ft (3 m) intervals. Caution: If no holes are available, contact tower manufacturer for applicable safety regulations regarding the drilling of any holes in tower sections.
