| While standard design principles call for pipes to enter a structure at a perpendicular angle, it is sometimes necessary to enter a structure at angles other than 90° to the wall of the structure. The maximum deflection angle determines if the pipe can physically be placed through the hole cutout. This is only a geometric check and does not indicate that a quality installation seal can be obtained. 
            		The data needed to calculate the Maximum Deflection Angle are: 
              		
                	- Wall Thickness of the structure
 
                	- Outside Diameter of the pipe
 
                	- Diameter of the hole cutout (always larger than the pipe 
                	OD.)
 
              		 
              		Enter the data into the calculator and click the "Calculate" button.
