Slope Base Flange, also called angle base flange, is used to set up the upright at an angle between 30° – 45°.
 
This fitting should only be subjected to light loads which cannot be positioned at 90° to the applied load. Where greater load is required, clamp fitting #132 is normally used with the upright tube bent to the required angle.
