Join or “lap” marks may form during the pouring of molten glass in the globe manufacturing process. It is not unusual for these marks to
become visible. This is a common and normal occurrence for large explosion proof globes and does not affect performance. Take
extreme care not to cross-thread the fixture when installing into mounting accessory. Install fixture by threading into the mounting
accessory; the electrical contacts will automatically engage. Be sure the fixture is tight. This fixture is factory sealed.
