Abstract: A magnetic tethering apparatus includes an end cap. The end cap includes an opening at a first end of the end cap, an outer wall extending from the first end to a second end of the end cap in a first direction, a first mounting surface at the second end of the end cap configured to engage with a second mounting surface, an inner wall extending from the second end of the end cap towards the opening in a second direction, and a base wall surface at the first end extending radially from the inner wall to the outer wall in a third direction transverse to the first direction.
