A retention apparatus, comprising:

• an attachment assembly comprising:
• a pivotable bar movable in a pivot direction to lock the attachment assembly to a component of a vehicle, and
• an actuation bar movable in an actuation direction to position the pivotable bar to unlock the attachment assembly;
• a support arm configured to couple to the attachment assembly, the support arm comprising a semi-ball shaped section;
• a curved plate configured to interface with the semi-ball shaped section;
• and
• a holder receiving the curved plate, the holder comprising:
• a first frame comprising a first edge configured to abut against a first side of an accessory, the semi-ball shaped section of the support arm received at least partially in the first frame, and the first frame pivotable relative to the semi-ball shaped section to adjust a position of the accessory.

A retention apparatus, comprising:

• an attachment assembly comprising:
• a pivotable bar pivotable in a first direction to lock the attachment assembly to a component of a vehicle, and
• an actuation bar movable in an actuation direction to pivot the pivotable bar in a second direction to unlock the attachment assembly, the second direction different than the first direction;
• and
• a support arm configured to couple to the attachment assembly, wherein the support arm comprises:
• a semi-ball shaped section configured to interface with a curved plate, wherein the curved plate is pivotable relative to the semi-ball shaped section to adjust a position of an accessory relative to the component of the vehicle, the semi-ball shaped section having a center of curvature that is positioned outside of an inner space defined by the semi-ball shaped section, and
• a rod section extending relative to the semi-ball shaped section.
