Abstract: Exemplary systems and methods for generating fluid distribution system solutions are provided. A user interface is provided that enables user to make selections relating to components and/or characteristics of a target fluid distribution system. The interface is configured to provide feedback based on user selections and verify that the selections are compatible. Exemplary systems and methods are configured to verify the user input and generate a target fluid distribution system solution based on the input.

Abstract: A spindle for a releasable securing device having a ball that cooperates with the spindle, which is located in a shank of the releasable securing device, is disclosed. The spindle includes a tapered land region and a ball pocket region. The tapered land region is configured to selectively contact the ball of the associated releasable securing device urging the ball outwardly in a radial opening formed in the shank of the associated releasable securing device. The land region includes an external surface tapering toward a central axis and a distal end of the spindle. The ball extends beyond an outer surface of the shank when contacted by the exterior surface. The ball pocket region is spaced from the tapered land region toward a proximal end of the spindle.
