Angle mount has 45° of motion. The
extension lengths shown are minimum

pitch and fan diameter. Other considerations
must be evaluated when determining
extension requirements, such as placement
of lights, sprinkler systems, HVAC systems,
etc. In addition, OSHA requirements state
that fan blades must be a minimum of 10'
above the floor.
