The aluminum ALTA PH-32 3-Way Pan Head from Vanguard is a 1.5 lb Arca-type compatible support that has a load capacity of 11 lb. The head has two separate handle locks, one for the vertical tilt and the other handle locks the lateral tilt and panning simultaneously. The front tilting range is -60° to +90°, the lateral range is -30° to +90°, and the head can rotate a full 360°. In addition, the 5.2" tall support has two bubble levels, and includes a quick plate with a safety pin, which prevents the plate from sliding or falling out if the clamp was partially opened by accident.
