Collapsible pin

Abstract:

An apparatus includes a first pin half, a second pin half opposite the first pin half, and a center pull pin disposed between the first and second pin halves. The first and second pin halves each include a first end, a second end opposite the first end, a bottom portion proximate the second end, and a middle portion adjacent to the bottom portion. The bottom portion extends in a radial direction a first distance. The middle portion extends in the radial direction a second distance less than the first distance. The center pull pin is removable from between the first and second pin halves. The first and second pin halves are collapsible towards each other when the center pull pin is removed from between the first and second pin halves.
